What is GPU virtualization?

Virtual machines utilize hardware resources such as vCPU and vRAM. The vGPU or virtual GPU, on the other hand, enables virtual machines to access one of the physical GPUs of the host simultaneously. GPU virtualization is a technology that accelerates graphics or applications running on a virtual machine using a GPU. This involves the use of various techniques such as device emulation and remote API.

This can also bring great benefits by making the system more efficient. This enables better utilization of hardware resources among different virtual machines. In fact, with just the host system, you would not really be taking advantage of all those resources. Especially if the workload is not at its maximum level. This is something we already see in VPS.

GPU virtualization reduces CPU usage by enabling virtual machines to utilize this hardware resource. This happens because the software doesn’t use graphics acceleration. In essence, GPU virtualization enables the same utilization of physical GPUs as with other resources, allowing for rendering and other virtual machine tasks. Hardware graphics acceleration is thus made possible.

Advantages of GPU virtualization

GPU virtualization can not only improve efficiency and performance. In fact, it also has other advantages, especially for data centers or VPS servers. For example, the following should be noted:

• Performance: GPU virtualization improves the performance of virtual machines. Especially everything related to graphics, in addition to accelerating tasks such as AI, ML, GPU computation, etc. Additionally, by reducing the CPU workload by not having to use software acceleration, overall performance is better
• Reduces bottlenecks: Recall that it reduces the workload on the CPU. So it allows the system to perform more smoothly at peak workloads. Virtual machines will be able to better distribute the workload between the CPU and GPU. This ensures a more robust performance.
• Greater wealth:by being able to use applications that rely on GPU capabilities, this can enhance the richness of the virtualized system. For example, being able to run video games, AI software, GPU rendering. It also includes tasks that can make use of the GPU. The GPU decodes some of them instead of the slower CPU.

Ultimately, this allows virtual machines to perform increasingly better and closer to physical machines.

Techniques used in GPU virtualization

As mentioned above, there are several techniques used for GPU virtualization. The most important ones are:

• Remote API: is a technique that allows communication between the graphics API for call forwarding. That is to say, when an application is used in the virtual machine that makes use of graphics, the calls to the graphics API will be forwarded so that they can be attended by the graphics API of the host system. They can then be processed by the GPU. This technique is not perfect. Indeed, call forwarding compromises performance and prevents the virtual machine from being fully isolated from the host system. On the other hand, there is third-party software that can also add support for specific APIs, such as VMGL for OpenGL, rCUDA for CUDA, and so on.
• Fixed pass-through or GPU pass-through: This fixed pass-through is when a single virtual machine directly accesses a GPU on an exclusive and permanent basis. In this technique, performance is better. Indeed, it achieves 96-100% of native performance. In addition to high fidelity. In other words, it is superior to the 86% performance achieved by the previous technique. However, the downside is that multiple virtual machines cannot share the same GPU. That is, each one should have its own additional physical GPU. Consequently, this increases the cost of the required hardware.

Others technique

• Mediated transfer: This technique allows the GPU hardware to provide contexts with virtual memory ranges for each virtual machine through the IOMMU. As a result, the hypervisor will send the graphics commands from the virtual machines to the GPU. In other words, it is like a kind of partitioning of GPU resources. In this way, they will directly serve the virtual machines. This would be in between the two previous techniques. That is, without the need for API call forwarding, but being able to allow all virtual machines to make use of the same GPU. Technologies such as NVIDIA vGPU, AMD MxGPU, Intel GVT-g, etc., support this capability.
• Device emulation: As GPU architectures are very complex and constantly changing, it is not feasible for hypervisor software developers to virtualize new generations of GPUs in a complex way. It is only possible to do so with some older and simpler models, such as the 3dfx Voodoo2, the S3 ViRGE/DX, etc. This allows that if the virtual machine does not have 3D graphics acceleration, it can at least have a minimum functionality to access these machines through a graphics terminal.

Conclusion

GPU virtualization is a technology that allows multiple users to access and share the same GPU resources. It can support various applications, including machine learning, gaming, data visualization, and more. Benefits include increased efficiency in resource utilization and improved scalability of computing performance. By providing secure access to GPUs from different locations or devices, it also helps reduce costs associated with hardware investments while still delivering high-performance results. In conclusion, GPU virtualization provides many benefits that make it an ideal solution for businesses looking to maximize their computing capabilities without breaking the bank!

Browsers to enter the Dark Web

If we talk about the most popular and used browsers, Google Chrome, Mozilla Firefox or even Edge probably come to mind. But there are many more. Some of them have a very small market share, but they may have very different features from the most popular cases.

When surfing the net, we can use any browser. It is clear that this is its main function. But if we talk about browsers that allow us to enter the Dark Web or surf anonymously, the number is reduced. They can also help to improve security and avoid certain problems that can damage the operation of our computers.

Tor Browser

Undoubtedly, one of the most popular browsers for accessing the Deep Web is Tor. In fact, it was the first browser that came out for this purpose. Moreover, it is totally based on privacy and security. It is even today one of the preferred options for those looking for an alternative to the most popular ones.

The Tor browser allows you to browse the Deep Web. It is available for most operating systems such as Windows, macOS, Linux or Android. It can help us to improve privacy on the network. This is independent of whether we can enter the Deep Web. We can use it on desktop computers and also on mobile devices completely free of charge.

We can download the Tor browser from its official website. There we will find the different versions available. As we always say, we recommend downloading this type of programs from reliable sources.

Subgraph

Another option we found is Subgraph. This is an open source browser that allows you to enter the Dark Web. It is based on Tor, but in this case we are dealing with an operating system and not just a browser.

It has a very restrictive privacy policy. This means that many users rely on this tool to surf the web when they are looking for maximum security. It has a file encryption system and even comes with an instant messaging program. You can find all the information on its web page.

I2P

There is also the I2P alternative. It also works through layers to achieve private and secure browsing. It is based on a tunnel system so that data can travel without being intercepted. A way to encrypt that information and prevent it from ending up in the hands of third parties that could harm our privacy.

Both the sending and receiving clients will use a tunnel. In this way, messages can be sent and received fully encrypted. In addition, there is no possibility that the information can be filtered. It acts, in a way, as a VPN. In short, I2P is an interesting option if you are looking for anonymity on the network. More information can be found on their website.

Whonix

A more unknown option is Whonix. It is a browser that is available for Windows, macOS, and also Linux. It allows us to surf the web anonymously. Once again, this is an option based on the Tor browser. It has a system that prevents our IP address from being exposed when browsing. This is achieved by using a virtual machine. This should be noted. In effect, it is part of an operating system rather than a standalone browser. A different alternative to others we have shown previously.

Another very interesting thing about this browser is that it also has its own operating system, based on anonymity. This is formed by two virtual machines, where one of them is dedicated to run a Tor proxy, which does the function of gateway. And the other virtual machine is called Whonix-Station, which is located in an isolated network. It is a simple system to install if you have slight knowledge about Linux or this type of system.

Advantages and disadvantages

This brings some benefits. The most striking is that it will be extremely difficult for an attacker to know our IP. Indeed, all incoming and outgoing connections go through the Tor network. This also includes applications that do not support the proxy. In this case, it is done by Firewall. This also protects us against root exploits. But in the event that one manages to infect our computer, the system itself ensures that it does not affect the integrity of the processes.

Whonix can be used with a VPN or SSH connection, as all serial numbers will be hidden. This includes the computer where the Virtual Box is running, or the virtualization service we use. At the same time, this operating system has some disadvantages. To go further, it is very slow to perform updates. In addition, it requires a lot of resources on the computer to work properly, this in terms of CPU and RAM. Logically, since the computer will be running two virtual machines instead of one as usual. But on the other hand, we have all the advantages offered by Linux-based operating systems. For example, the apt-get packaging tool, which allows us to install all kinds of new tools.

Tails

Like the vast majority of dark/deep web browsers out there, the Tails darknet browser is again based on the original Tor browser. However, this build could be better defined as a live operating system. Especially since it can be booted and accessed from a USB stick or DVD without installation.

This then relies on the use of highly advanced cryptographic tools to add the protective layers that ensure you remain hidden as you browse the Internet. This includes all files, messages, videos, images, and emails sent and received by you and your accounts. To maximize the level of security you have while browsing, Tails Onion Browser Dark Web will automatically shut down and temporarily stop the use of any operating system you are currently using. This really minimizes the risks of being discovered.

Of course, all of this will return to normal once the Tails system has been shut down. Don’t worry, only RAM is used to run this operating system, and the hard drive and disk space will remain intact. While Tor may be the most popular hidden web browser, the Tails operating system is, in fact, one of the best.

But the truth is that little by little its importance and presence in the market has been growing. This has been helped by the good updates it has been receiving. In fact, it has made it a much more stable, reliable and fast operating system. Besides that, it has been incorporating new functions that its predecessor Windows 10 has not received until the moment and that, surely, it will never arrive to have. Anyway, if you are still undecided to install Windows 11 on your computer, we are going to leave you with a few reasons why you should install it right now.

Reasons why you should upgrade to Windows 11:

• Appearance
• File Explorer
• Integration
• DirectX 12
• Direct Storage
• Snap
• Multiple desktops
• Command bar
• Gaming performance
• HDR
• Security

Appearance

This new operating system has a different and differential aspect with respect to what we knew until its arrival. Microsoft remodeled a good part of its operating system, making it more modern and with a style of another level. In fact, it is something we have never seen before in Microsoft products.

Now in Windows 11:

• The redesigned taskbar comes with centered icons.
• There is a move towards transparency and a fading of colors in layers.
• The menus look more modern and closer to other operating systems that are more advanced in design.
• The taskbar, applications and file explorer windows change their appearance with any desktop background.
• New Widgets menu with news, notifications and other alerts, such as weather.

File Explorer

From major update 22H2 onwards, Windows 11 has introduced tabbed browsing in its File Explorer windows. This allows us to create as many tabs as we want within the same window. So we will be able to scroll through each one horizontally, copying and pasting files and folders from one to another. Also, we will be able to create groups of tabs. The best of all is that no matter how many we think, it will not affect the RAM or the performance of the computer.

Integration

After a world changed for everyone by the pandemic, technology had to evolve. Therefore, it had to change abruptly to adapt to what users needed. In fact, in the past, videoconferencing programs were moderately well maintained. They were only to be used once in a long time. Now, however, they are paramount and life is no longer conceivable without them. Indeed, Microsoft Teams has done well in this regard. Moreover, it is now integrated directly into Windows 11.

DirectX 12

DirectX 12 Ultimate is and will be the foundation of all features for the next generations of games that can run on Windows. Especially for those using features such as real-time ray tracing and mesh shading. Having DirectX 12 Ultimate will be a must for Windows gamers aiming for maximum quality. It is worth remembering that Windows 11 supports DirectX 12 Ultimate as a minimum specification requirement.

Direct storage

It is also a fact that the next generation PS5 and Xbox consoles are built on NVMe SSDs. Therefore, they reach really high speeds. Well, DirectStorage brings that technology to Windows 11 exclusively. This is what makes it completely different from the other operating systems that Microsoft has released.

Snap layouts

Snap layouts have been a characteristic that was released in Windows 7. However, it has been now in Windows 11 when it has reached its maximum splendor. Therefore, we will be able to order by symmetrical placements or not, serving us for several drawings to place the tabs that we have open.

Snap feature in Windows 11, allowing easy access to up to six different types of window layouts at any given time. Remember that availability depends on our monitor.

Multiple desktops

Windows 11 has a multi-desktop feature that can be accessed from the taskbar. In fact, just click on the Task View button to open multiple desktop instances that can even be renamed. In addition, we will be able to maintain its essential tasks to differentiate from the rest. You can reorganize them in any order, change their location, or close the ones you are not going to use anymore.

Command bar

One of the most applauded features in Windows 11 File Explorer is the command bar at the top of each window. We will be able to cut, copy, paste, rename and delete files by simply hovering the cursor near the top area. A brilliant idea and much faster.

Game performance

Windows 11 supports some of the latest enhancements in gaming features that are present today. This is something that other similar operating systems do not offer. In Xbox Gaming Pass, there are features that grant a substantial enhancement of the gaming experience. For this reason alone, it is a good reason to upgrade to Windows 11

HDR

Having HDR in a game is something differentiating, although not all of them are compatible. Windows 11 does support it, as it took Xbox’s Auto HDR technology and applied it to all DirectX 11 games (the newest ones) running on the operating system.

So Windows 11 supports HDR video streaming out of the box and allows you to use an automatic HDR option. After that, other circumstances must be met to be able to really enjoy it, such as game and screen compatibility.

Security

Windows 11 offers a much improved level of security compared to other versions. Especially because of three features that make it special in this regard.

• Kernel isolation: security based on virtualization, protecting the computer against malicious code.
• Trusted Platform Module (TPM): it is a prerequisite for installing Windows 11 to have the TPM 2.0 module in the security processor, thanks to which maximum cryptographic protection is achieved.
• Secure boot: Secure boot is enabled by default.

Obviously, Windows 11 will be the first to receive major updates and security fixes, so you should always have it up to date. With all that we have just told you, you have more than enough reasons to upgrade to Windows 11.

What is a Virtual Machine

A virtual machine is a software that creates an independent layer where the operation of a real computer is emulated. Additionally, it includes all the hardware components you need to run a different operating system or a specific application. It can be run in a window as a separate computing environment. A virtual machine works like a computer within a computer. Also, it and allows end-users to use apps as they would on an actual machine. It is an excellent tool for programmers, developers and IT professionals. Indeed, this environment allows you to create, deploy and manage applications and software securely.

What is Hyper-V

Hyper-V is a hardware virtualization product from Microsoft that allows users to create, run and manage virtual machines on a host operating system. In addition, Hyper-V provides hardware virtualization. As a result, each virtual machine runs on virtual hardware. It also allows multiple operating systems to be created and run on a single physical machine. In addition, Hyper-V also allows users to perform system administration tasks such as backup, restore, and migration of virtual machines.

What are the requirements for using Hyper-V?

The first thing to know is that Hyper-V is available as an optional feature in Windows 11 Pro, Enterprise, and Education. If you don’t know what version of Windows you have, you can find out by going to Settings>System>About. Then check the Windows specifications section to find your edition of Windows. But we must not only have a compatible Windows. In fact, we must also enable hardware virtualization in BIOS. This function is usually disabled. Therefore, we must be the ones to enable it.

When should we use Hyper-V?

There are some cases in which we could use Hyper-V. In this way, not having to rely on another third-party tool such as VirtualBox or VMware Workstation.

• Run and test an older version of Windows or a non-Microsoft signature operating system.
• Test software on multiple operating systems using many virtual machines on a single host system.

Enabling hardware virtualization in BIOS

As we have told you before, for everything to work perfectly, the hardware virtualization part of the BIOS must be operational and enabled. To perform this task, you should consult the user manual. Indeed, each brand uses a different way to enable this function. For knowledge purposes, let’s assume you have a computer from a well-known brand, such as HP.

• Turn off the computer.
• Now we turn on the system and start pressing the Esc key to see the boot menu.
• It is time to press F10 to enter the BIOS Setup.
• In the BIOS Setup Utility, we use the arrow key and open the Setup tab.
• Next, we go down to the Virtualization Technology option.
• Press Enter and then click on Enable.
• Press the F10 key to save the changes and exit.
• The computer will restart, and the virtualization tool will be enabled.

Hyper-V on Windows: control panel

Now it is the turn of Windows 11 and the ways that we have to enable the Hyper-V. The first one is by using the Windows Control Panel as follows:

• Press Win + R to open the Run dialog.
• Type Control Panel and open the option that pops up.
• Now go to Programs>Programs and Features.
• In the left pane, we click to Turn Windows features on or off.
• Now, in the Windows Features dialog box, we select Hyper-V.
• We must make sure that when we expand this option, Hyper-V Management Tools and Hyper-V Platform come up as active.
• Then we click on OK.
• As these are optional features, Windows will begin to install and enable them on the computer. This process may take some time to complete.
• When it is finished, click on Restart Now.

Hyper-V on Windows: Command Prompt

Another way to perform this same action is to use the Command Prompt. DISM is used to get Hyper-V running on the computer.

• We write cmd in the task bar and when the option appears we click on Run as Administrator.
• Now that we are inside the Command Prompt, we write the following: DISM /Online /Enable-Feature /All /FeatureName:Microsoft-Hyper-V
• Once we press Enter, it will start enabling the Hyper-V feature, and we will see the progress on the screen.
• Once the operation completes successfully, you will need to reboot your PC. Then, press Y on your keyboard to confirm the action.

Hyper-V on Windows: Windows PowerShell

It is certainly a simple process with the command prompt. On the other hand, with Windows PowerShell it will be equally easy.

• In the search box of the taskbar, we write PowerShell, and we give to Run as administrator as soon as it comes out.
• Already in PowerShell, we write the following command, and we press Enter: Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All
• PowerShell will start the Hyper-V enablement process. If successful, we will be prompted to restart the PC.

These are the ways we have to enable Hyper-V in Microsoft’s operating system. As you have seen, it is very simple, surely much more than you expected, to have Hyper-V fully operational in Windows 11. This way you can enjoy the benefits of virtualization on your computer. With the added bonus of not having to purchase or download additional software. See you soon!

What is a virtual machine?

A virtual machine (VM) is a software implementation of a computer that runs on another computer. This way, allowing multiple operating systems to run on the same physical machine. It provides a virtualized environment for running applications, which are isolated from the host operating system and other VMs.

How a virtual machine works?

A virtual machine works by using a hypervisor, also known as a virtual machine monitor, to virtualize the underlying hardware of a physical computer. The hypervisor creates virtual devices and emulates their behavior. This way, it can to provide a virtual environment for the operating system and applications running within the VM. The VM communicates with the hypervisor, which in turn communicates with the physical hardware. So it allows the VM to access physical resources such as CPU, memory, and storage. This allows multiple VMs to run on the same physical machine. Also, each one with its own operating system and applications, without interfering with each other.

What are the advantages of using a virtual machine?

Some advantages of using a virtual machine include:

• Isolation: VMs provide a layer of isolation between the host operating system and applications. Therefore, reducing the risk of contamination or system instability.
• Cost-effectiveness: VMs can be a cost-effective solution for running multiple operating systems and applications on the same physical machine. This way reducing the need for multiple physical computers.
• Portability: VMs can be easily moved between physical machines, making it easier to migrate to new hardware or to recover from a failure.
• Compatibility: VMs can run older or incompatible applications, allowing them to continue to be used even on newer hardware or operating systems.
• Test environment: VMs are available to create a safe and controlled environment for testing new software or configurations without affecting the host operating system

Disadvantages of working with virtual machines

Some disadvantages of working with virtual machines include:

• Performance: VMs can have lower performance compared to running directly on physical hardware, as they must share the physical resources of the host machine.
• Resource utilization: Running multiple VMs on a single physical machine can consume a large amount of resources. Especially memory and storage.
• Complexity: Virtualization can introduce additional complexity to an IT environment, requiring specialized knowledge and skills to manage and maintain the virtual infrastructure.
• Licensing costs: Some virtualization platforms and operating systems have additional licensing costs that can add to the overall cost of implementing virtualization.
• Security: VMs can be vulnerable to security threats just like physical computers. Therefore, additional security measures may be required to secure the virtual environment.

What are the requirements for Windows to run virtual machines?

The requirements for Windows to run virtual machines are:

• A 64-bit processor with Second Level Address Translation (SLAT)
• At least 4 GB of RAM
• At least 64 GB of free hard disk space
• Hyper-V and Containers Windows features enabled
• Windows 10/11 Pro or Enterprise (64-bit) version 1909 or later
• A GPU with WDDM 2.0 driver for GPU acceleration (optional)

What is Hyper V, the virtualization module for windows?

Hyper-V is a native hypervisor from Microsoft that provides virtualization technology for creating and running virtual machines on Windows operating systems. It allows multiple operating systems to run on a single physical machine. In the same way, providing isolation and security for each virtual machine and enabling efficient utilization of hardware resources. With Hyper-V, users can create and manage virtual machines. Also configuring virtual switches, storage, and network interfaces, and monitor virtual machine performance and resource usage. It is available as a feature in Windows 10/11 Pro and Enterprise editions.

What are the most used virtualization software?

The most widely used virtualization software are:

• VMware vSphere
• Microsoft Hyper-V
• Citrix XenServer
• Oracle VirtualBox
• Red Hat Virtualization (RHV)
• Proxmox Virtual Environment
• KVM (Kernel-based Virtual Machine)
• AWS (Amazon Web Services)
• Google Compute Engine
• Alibaba Cloud Elastic Compute Service (ECS)

They are certainly the most popular. However, we will highlight those most commonly used in Windows environment. Previously, we talked about Hyper V. Therefore, we will start with Virtual Box.

Oracle Virtual Box

VirtualBox is a free and open-source virtualization software for x86 and AMD64/Intel64-based computers. It allows users to run multiple operating systems on a single physical machine. Also, each one in its own virtual environment. Moreover, providing isolation and security for each virtual machine. VirtualBox provides a user-friendly interface for creating, configuring and managing virtual machines.

In addition, including support for storage and network interfaces, and can be used for a wide range of purposes including software development, testing, and personal use. It can run on various host operating systems including Windows, macOS, Linux, and Solaris, and supports a wide range of guest operating systems including Windows, Linux, and BSD distributions.

VMware vSphere

VMware vSphere is a comprehensive enterprise-class virtualization platform. It provides a centralized management solution for virtual infrastructure. Moreover, it is used for creating, deploying and managing virtual machines, networks, and storage resources. With vSphere, IT organizations can pool and allocate shared resources to virtual machines and application. With this in mind, enabling efficient utilization of hardware resources, high availability, and disaster recovery.

vSphere includes features such as live migration of virtual machines, storage and network resource management, and multi-hypervisor support, as well as a robust security model and a powerful API for integration with other management tools. It is widely used in data centers and cloud environments for virtualizing business-critical applications, and is available as a standalone product or as part of the VMware Cloud Foundation, a unified SDDC platform for deploying and managing a hybrid cloud.

Very well, in this way we have seen what Virtual Machines are. We also check what are the advantages and disadvantages of using them. We also learned how they work. Furthermore, we saw which are the most used ones, plus what you need to run them on Windows.

In this case, the interesting thing about it is that it uses a wide range of antivirus scanning engines to check the files we upload. All this can be very helpful to make sure that these files are clean before running them locally on the PC. Keep in mind that an infected file can affect the entire operating system.

Scan the content with your antivirus

We have already told you many times that it is advisable to have an antivirus installed on your PC. In addition, it must be properly updated to respond to the latest malicious code. This means that our local security software should be the first way to detect a virus in suspicious files. Generally, these programs allow us to scan both the operating system as a whole. But also in a specific file, which is what we are interested in now. In this way, we can largely rule out that the content we suspect is infected by some type of malware.

Send the suspicious files to VirusTotal

Since this website makes use of a multitude of different antivirus engines, as you can imagine, the effectiveness increases considerably. Typically, when we scan a local file on our computer, we do it with the only antivirus we have installed. In addition, it is a completely free service that we can use as many times as we need without spending a single dollar. It must be said that this service offers a comprehensive report with the results obtained by each of the antivirus engines. It is true that sometimes here we find false positives from time to time.

Thus, all we have to do is access the VirusTotal website. Once there, just click on the Choose file button. This way we select the content we want to analyze. Once this is done, we will have to confirm the upload of the selected file. After a few seconds, the website will present us with a complete report with each of the results of the scans independently.

Uses a virtual machine

In recent times, programs focused on the virtualization of operating systems are more widespread than ever. Here we can load any system to carry out all kinds of tests. And best of all, this does not affect the original operating system of the PC. Therefore, as you can imagine, this will be extremely useful when analyzing any suspicious file that we are going to download from the Internet, for example. In this way, we can perform all kinds of tests and analysis on it in the virtual machine without endangering the original system. In the case of detecting any positive, we will already know that we should not download that particular file to our computer.

Ultimately, we have seen 3 ways to know if a file has a virus. See you!

Should we upgrade?

I want to emphasize that the purpose of this post is not to encourage you to upgrade, or not to upgrade, to Windows 11. At the end of the day, it is a personal decision according to one’s own needs. We truly would like to put an end to numerous myths. This way, you will be able to decide for yourself what you want to do. On the other hand, you can always try this operating system and then go back to Windows 10.

Windows 11 is a must if you are going to use Intel Alder Lake processors.

Intel Alder Lake processors marked an important turning point in the x86 CPU industry. Indeed, the chip giant managed to recover from the slip it had with Rocket Lake. It therefore shaped a generation of much more powerful processors, with a higher number of cores and threads and more efficient operation. This was made possible by the leap to a hybrid design with high-performance and high-efficiency cores, and the use of the 10 nm SuperFin node.

To manage it properly, the company integrated Intel Thread Director into the Alder Lake processors. We are talking about a solution that operates at hardware and software level. In addition, it is designed to perform an optimal scheduling of the tasks that are being faced at all times. In this way, it is possible to assign these tasks to high-performance cores or high-efficiency cores in the most efficient way possible. Furthermore, it adapts to the particularities of the equipment in real time.

The operating system therefore relies on the information it receives from Intel Thread Director to distribute each task. This is essential for Intel Core Gen12, based on this hybrid design, to develop its full potential at all times. However, a myth has arisen around this technology. Specifically, that it was only possible to use the new Intel Core Gen12 processors with Windows 11. It has even been said that these processors have performance problems with Windows 10. Besides, if you want to continue with Windows 10, you can be totally relaxed.

Windows 11 performs much worse than Windows 10

This is one of the most important myths that remain until now. Indeed, it is one of those that is holding users back from upgrading from Windows 10 to Windows 11. Surely, you have seen tests where Windows 11 performed worse than Windows 10, especially in case of games. Surely, they are true. However, there is a determining factor. And that is that those tests were done with VBS enabled.

VBS stands for Virtualization-based Security. This is a security feature that allows Windows 11 to use hardware virtualization to isolate a secure region of memory. Once there, it will host important security features, most notably virtualization-based code integrity protection. When this feature is enabled, performance drops noticeably in Windows 11. However, if it is disabled, everything returns to normal.

With this feature disabled, performance differences between Windows 10 and Windows 11 are minimal in most cases. Of course, as long as we have a computer that meets the minimum requirements of each operating system.

You can only upgrade for free to Windows 11 from Windows 10

Many users believe that they cannot upgrade to Windows 11 for free because they are running Windows 7 or Windows 8.1. Certainly, it is not possible to make a direct update from Windows Update, as it would happen if we had Windows 10. However, this does not mean that we cannot make the leap to the new Microsoft operating system taking advantage of our Windows 7 or Windows 8.1 license. We can do it, but the process is different.

If we have Windows 7 or Windows 8.1, and we have a valid license, we will be able to use this license to activate a copy of Windows 11. This is working from October 2021 to the present date. However, I cannot guarantee that it will be if forever.

Updating

To install and activate a copy of Windows 11 if we use Windows 7 or Windows 8.1 we must follow these steps:

• We look for the activation license of our copy of Windows 7 or Windows 8.1. We put it to good safekeeping, since we will need it later.
• Furthermore, we make a backup of all our data and files, since we will have to make a clean installation of Windows 11. Note that we make a backup of all our data and files, since we will have to make a clean installation of Windows 11.
• Go to the official Microsoft website and create a Windows 11 installation media following the steps below
• We boot the PC from the USB drive and start the self-guided installation process. When choosing which version of Windows 11 we want to install, we must choose the one that matches the version of Windows 7 or Windows 8.1 that we had.
• When we are asked for the activation key, we introduce the license of our previous operating system and ready. We can also postpone this step and carry out the activation after the installation of Windows 11.

It is important to note that you will be able to install Windows 11 in this way even if your PC does not meet the minimum requirements of such operating system. However, this implies certain risks. Theoretically, it appears that Microsoft is not going to leave without support those who install Windows 11 without meeting the minimum requirements. Nevertheless, this could change in the short, medium or long term, and you could also encounter stability or security problems at some point.

If you do not meet the minimum requirements, you cannot upgrade to Windows 11.

Windows 11 has marked an important leap in terms of minimum requirements. Especially, if we compare it with Windows 10, since it asks for twice the RAM (4 GB instead of 2 GB). In addition, it needs a storage unit of at least 64 GB capacity. It requires a DirectX 12 compatible GPU with the WDDM 2.0 driver and also requires a TPM 2.0 chip. Or an alternative solution, such as fTPM for AMD processors or PTT for Intel chips.

When Windows 11 was announced, it was not clear to us whether its requirements would be mandatory or not. That is to say, if they would represent an insurmountable barrier that would prevent the installation of this operating system in case of not fulfilling them or if the opposite would occur. In the end, the latter was fulfilled. That is to say, you can install Windows 11, although your equipment does not fulfill all its minimum requirements. However, you must bear in mind that you will not be able to do it directly from Windows Update. For what, you will have to make a clean installation.

As we have already mentioned in the previous point, installing Windows 11 on a computer that does not meet the minimum requirements is perfectly possible. Personally, I have installed it on computers with processors as basic as a 5th generation I3. Furthermore, I have not experienced any problems during the installation process or in the first few minutes after completion.

However, it is advisable to remember the previous point. Indeed, Microsoft is still not entirely clear about what might happen in the medium and long term with these users. So in the end, it remains a risk.

Windows 11 only works well on high-end PCs

This is also not true. Indeed, you do not need a mighty PC to enjoy a good user experience with Windows 11. Certainly, this operating system is more demanding than Windows 10. Let’s remember that, unlike Windows 10, it does not work really well on configurations with only 4 GB of RAM.

Consequently, if you have a PC that meets the minimum requirements of Windows 11, you will be able to make basic use of it. However, the experience will not be optimal. But this doesn’t mean you have to use a state-of-the-art pc with 16 GB of RAM and a Core Gen12 or a Ryzen 5000. Some configurations like 8 GB of RAM and Core i5 8400 and Ryzen 5 2600 processors work really well.

In short, any low-mid range PC that meets the minimum requirements, and has at least 8 GB of RAM, will be able to run Windows 11 well. Anyway, in this way we have dismantled some myths about Windows 11. I hope this information will help you to make the right decision. At the end of the day, it is a personal decision motivated by your circumstances. Goodbye!

Some actions to improve the performance of Windows 11.

Next we will see some options to smooth the behavior of Windows 11.

Get rid of applications you don’t need

There is an explanation for this. Indeed, some applications can consume resources in the background even if you don’t use them. Moreover, even if you force close them, they reappear in the process list. There are also Microsoft’s own applications that affect this. For example, OneDrive, very useful but if you do not use, it can become a nuisance. So, deleting them will help us to free up resources, and to definitively prevent them from returning to the background. Please follow these steps:

• Press Win+Q combination and run Add or remove programs.
• A list of installed applications and programs will appear. We only have to choose the ones we want to delete and execute the action.

How does this improve the performance of Windows 11? By removing these applications, we free up resources and ensure that they will not be consumed by them again. Moreover, other programs benefit from these freed resources. In addition, the system gets more available space.

Frees up hard disk space

Maintaining the hard disk is an elementary task. Especially if it is an SSD. It has been proven that they end up losing performance as they fill up. This occurs because such memory is slower than TLC memory. In addition, as we fill the unit, the total available cache is reduced. Consequently, if you use a drive of this type, it is advisable not to fill it to the top. There are several methods to free up space, but these are the simplest and most effective.

• Remove applications following the steps explained in the previous point.
• Find folders that contain videos, photos, or other large files that you don’t need. Then click on it by pressing Shift and Delete at the same time. Then confirm the deletion.
• From the search menu, enter the term Disk Cleanup. Then choose the storage drive on which you want to free up space. As a result, a window will appear with the amount of space you can free up, and different additional options to maximize the freed space by deleting other things.
• We can also obtain a more complete image using the storage sensor. In this way we can get concrete information about what we want to remove. Just search for storage from the search menu.

Certainly, this action helps to improve system performance. By reducing the occupied cache, it allows the unit to work faster. It is best to leave at least 10% to 20% of the total capacity of an SSD free. This may seem complicated. However, there are methods to achieve this. For example, we can resort to cloud storage. We can also expand the storage capacity of the SSD.

Reduces graphic effects and animations

Another classic that Windows 11 inherits from Windows 10. The new Microsoft operating system has an improved interface, much more attractive and with prudent nuances. Indeed, there are first-class animations, transparencies, blurs, acrylic materials to better unify the interface. In short, these changes imply a higher consumption of resources. Reducing the system’s pretty side will help us improve the performance of Windows 11. Let’s see how to do it in a simple way:

• Press the Win+I combination to go to Windows Settings.
• Once there, click on Personalization
• Now in the left column, click on Accessibility. We disable transparency effects and animations.
• Finally, follow the next path: View advanced settings>Advanced>Performance>Settings>Visual Effects>Adjust for best performance.

We improve Windows performance by reducing the graphical load on the operating system. Consequently, the demands of the operating system and its resource consumption are minimized. You will have a less beautiful, but faster Windows 11. This can make an especially big difference on less powerful computers.

Disable the VBS option

Windows 11 comes with VBS, i.e., virtualization-based security. This is a feature that helps protect the operating system against malware. It is also part of the Hypervisor-Enforced Code Integrity layer, known as HVCI. Undoubtedly, its security benefits are many. However, it can noticeably reduce system performance, especially in games. Disabling it would make a big difference, and that is why we offer you this option. To disable this technology, just do this:

• From the Windows menu, find and run Core Isolation.
• Enter the first result and disable the option that will appear. If nothing appears, or you do not have access, do not worry, it indicates that it is already disabled.
• Restart the computer for it to take effect.

As we told you, this technology consumes resources and slows down the computer’s performance, so disabling it means that it no longer produces these negative effects. It is true that it significantly improves security, but for a normal user it is not essential, far from it.

Do not install a third party antivirus

This may seem like a strange recommendation. However, Windows 11 comes with Microsoft Defender, a complete and effective security suite that is more than enough for an average user. With it, we will be able to make analyses, and we will have the tranquility that supposes to count on protection in real time. So Windows Defender is the best free antivirus.

Consequently, it is only a matter of uninstalling this antivirus from the list of programs. The advantage is that antivirus programs run in the background and can consume numerous resources, RAM, CPU, and network. Especially if they run in the background. Eliminating them will leave Microsoft Defender as the only antivirus solution, and its consumption of resources is minimal.

All right, ultimately we have seen how to improve the performance of Windows 11. It’s all a matter of common-sense and taking advantage of the potential of this system. See you soon!

How to create your own online database with Tadabase

Tadabase is a web application. Consequently, you do not need to download any software to use it, as it is accessed directly from the browser. Using it, we will be able to create a database without the need to have any technical knowledge or write a single line of code. We only need to be able to drag and drop the necessary components and then connect them to a database.

This customized database will serve to automate daily business activities. For this purpose, it has an approval process, compliance tracking, customizable dashboard, task management, workflow configuration, among other issues. The platform works by hosting the projects created on our personal subdomain created. There, we can upload at the same time a data file that we want to use to process the personal information we entered at the time, such as a program like Microsoft Excel.

To test this online application, simply create a free account. Then upload a data file in CSV format, information that will be treated as a warehouse. Something that we must emphasize is that at the beginning it may seem somewhat complex. However, as you get more practice, you will be able to drive with ease. Let’s take a look at some features.

New data table

A data table is a collection of data, similar to a spreadsheet. In fact, you just need to give a name for the table and the fields you want to record, such as Customers or Orders. Once the database has been created and configured, we can use the information it contains to create pages in the form of tables, forms, graphs, etc.

The same platform offers a page that serves as a template. Consequently, we can start from scratch with a design or edit the existing one. When we are going to create a new page, we will have to assign a name and choose its design. We will also have to configure other parameters.

Task automation

From this section we can create scheduled tasks to trigger customized or on-demand automated workflows. For example, we can send automated emails and schedule them. It is also possible to generate a script that we can use to display components of our application. For example, it can be used to view records on the company’s website, such as its inventory, public route time or its asset listings.

Subsequently, to the page that we are going to create, we will do it with the CSV data that we have loaded. Therefore, we will be able to add elements such as buttons, graphs, images, frames, etc. To do so, it will only be necessary to drag and drop the objects. Once finished, the page is saved, and we can share it thanks to the subdomain assigned at the beginning.

Insert plugins

This web application also has support for various plugins from its Pipes section. Indeed, it has a good number of categories such as Utilities, API, Forms, Marketing, Surveys, Project Management, Time Management, among others. In addition, there is compatibility with such popular tools as Slack, Twitter, Trello, Google, Calendar, among many others. In addition, several of them are configurable. To install it, you only need to click on the desired one and then click on the Install button.

Tadabase: is it really recommended?

I know what you are wondering. Does Tadabase really work to create our own database? Well, it is certainly an option to consider for those who need to create an online database but do not have programming skills. In addition, it provides the user with all kinds of tools to carry it out. Therefore, it is a web solution for our database low cost, high security and rich in features. Specially designed for people who know nothing about coding.

Tadabase Plans and Pricing

Tadabase provides a 14-day free trial period. The only thing we will need to do is to register for which we can use our email and password.
