How to Run Windows 10X on Your PC (Latest Build)

It’s 2021 and Microsoft has almost finalized the Windows 10X build for public release. Many reports suggest that Windows 10X is OEM-ready and it’s going to be shipped later this year. So if you have been waiting to try the latest build of Windows 10X then we have got good news for you. The near-final build of Windows 10X has been leaked and you can run it on your PC right now. In fact, we tested the latest build of Windows 10X (20279) on our PC and it worked quite well. So if you are also interested then go ahead and find out how to run Windows 10X on your PC from our detailed guide below.

Run Windows 10X on Your PC (2021)

Here, we have explained all the steps in great detail so anyone can run Windows 10X Build 20279 on their PC. I would recommend you to go through all the points to get a better idea about the installation process. You can click on the link below to move to the relevant part.

Things to Know

  • We are not going to install Windows 10X on physical hardware as the ISO image is not out yet. However, we can try the nearly-final build of Windows 10X through a virtual machine. Unlike the official emulator, the performance is much better on the virtual machine.
  • We are going to use a VHDX file (Hard disk image file) which can only be used on Microsoft’s Hyper-V application and it’s only available on Windows 10 Pro. So in tandem, you need Windows 10 Pro, Enterprise, or Education to run Windows 10X on your PC.
  • Currently, you can’t run Windows 10X on third-party virtual machine applications such as VirtualBox, VMware, QEMU, etc.
  • Hardware virtualization support is mandatory through BIOS or UEFI.
  • If you have an AMD GPU then you can’t run Windows 10X virtual machine. However, we have found a workaround and you can find the solution below.

Set Up Hyper-V

1. First off, you need to enable virtualization from your BIOS settings. While rebooting your PC, you need to press the BIOS key which will open the BIOS settings page. You can find the BIOS key from our below table. If the below key is not working then look for the specific BIOS key for your PC manufacturer on the internet.

2. Once you are on the BIOS page, you need to enable “Virtualization”. Every PC has a different name for the virtualization technology so look for “Intel VT-x”, “Intel VT-d” or anything on similar lines. Move between different menus and enable virtualization and save the changes by pressing the F10 key.

3. Once you have done that, your computer will reboot to Windows 10. Now, we have to enable Hyper-V on your Windows 10 computer. To do so, press Windows and R keys at once to open a Run window. Now, type optionalfeatures.exe and hit enter.

4. Here, scroll down and look for Hyper-V. Now, enable all the checkboxes under Hyper-V and hit the OK button. It will start installing the necessary packages and will ask you to restart the computer once the installation is done.

5. You have successfully enabled Hyper-V on your Windows 10 computer. To open it, just press the Windows key once and type “Hyper-V” in the search bar and you would find the application on top. Click on it.

6. This is how Hyper-V will look like.

7. Now, you need to download the VHDX file created by thebookisclosed on Twitter. You can click here to download the file directly.

8. After downloading the file, extract the ZIP file and move the Flash.vhdx file to an accessible location like Desktop. I would recommend you to save it where there is ample storage available.

9. Now, come back to Hyper-V and click on “New” and select “Virtual Machine” from the top-right pane.

10. After that, give a name to the virtual machine. I have named it “Windows 10X”, but you can choose your own.

11. Next, choose “Generation 2” and hit the “Next” button.

12. After that, allot RAM to the Windows 10X virtual machine. I would recommend you to allot 3GB (3072MB) or more for better performance.

13. On the next page, choose “Default Switch” from the drop-down menu and hit “Next”.

14. Finally, click on “Use an existing virtual hard disk”  and select the “Flash.vhdx” file by clicking on the “Browse” button.

15. Finally, click on “Finish“.

16. Now, this is the virtual machine that we will use to run the latest version of Windows 10X on our PC.

Run Windows 10X on Your PC

1. Right-click on the virtual machine and choose “Connect“.

2. After that, click on “Start” and Hyper-V will start the Windows 10X virtual machine directly from the VHDX file. On the first run, it will take some time to process all the files and information.

Note: Even after 30 minutes, if the VM is stuck on a black screen then you are most likely using an AMD GPU. Go through our next guide to find a solution.

3. Finally, you will be greeted with a Windows 10X boot animation.

4. Now, go through all the on-screen instructions and login with your Microsoft account. You can also create a PIN during the initial setup.

5. Now this is what the nearly-ready Windows 10X looks like on a single screen. It looks quite promising, right? To learn more about the final build of Windows 10X, go through our first impressions below.

6. If you want to stop the virtual machine then click on “Action” at the top-row menu and choose “Turn off“.

7. And if you want to delete the Windows 10X virtual machine then right-click on the VM and choose “Delete“. That’s it.

Run Windows 10X Virtual Machine on AMD GPU

Currently, there is no way to run the Windows 10X VM without disabling the AMD GPU altogether. You will have to use the integrated GPU that comes with the Intel chipset to run Windows 10X. And yes, the performance will take a hit due to the lack of a powerful GPU. Nevertheless, if you want to taste the finalized version of Windows 10X on an AMD GPU then here is how to go about it.

1. Right-click on the Start Menu and open “Device Manager“.

2. Here, expand the “Display adapters” menu. Now, right-click on the AMD GPU and disable it.

3. Finally, start the VM in Hyper-V Manager and this time, Windows 10X should boot fine.

Windows 10X First Impressions

Windows 10X, in its near-final version, is unlike anything that we have experienced in a Microsoft product. It’s polished right from the boot screen to the onboarding setup. In terms of design and aesthetics, Microsoft has really done a great job and developed a consistent UI across the board. Some would say that it looks like Chrome OS and that would be partly true. However, I am happy that Microsoft ventured to bring a lightweight OS to the masses.

Now coming to the million-dollar question: does the final build of Windows 10X support Win32 apps? Unfortunately, there is no support for legacy Windows apps on Windows 10X. It’s surprising though. In an earlier build of Windows 10X, there was support for Win32 apps through the container so why Microsoft removed it is beyond our understanding.

Also, it’s hilarious that you can run legacy Windows apps on Chromebook via Wine, but can’t run native Windows apps on Windows 10X. Hopefully, before the final release or a year down the line, we might get legacy app support through improved x86 emulation. For now, I can say that it performs really well, has beautiful UI and animations, but the lack of Win32 apps (even containerized) might push the much-hyped OS to oblivion just like Window 10S.

Install Windows 10X on Windows 10 and Experience the New UI

So that is how you can run Windows 10X on your Windows 10 PC and explore the new UI that is most likely coming to Windows 10 users through the Sun Valley update. Since I use Chromebook as my daily driver, I found the Windows 10X experience strikingly similar to Chrome OS. And that is not a bad thing.

I just hope either Win32 apps make a comeback in the near future or Microsoft pushes developers to release new build of their apps which are compatible with Windows 10X. Anyway, that is all from us. If you are facing any issues then let us know in the comment section below. We will surely try to help you out.

  1. Hello, a good job of running Windows 10 X in virtual machine in Hyper-V, but I have a question Why can I not shut down Windows 10X in Hyper-V, the operating system in Wondows 10X?

  2. When I start the Virtual Machine connection it’s shows this error: “Not enough memory in the system to start the Virtual machine Windows 10X.”
    “Could not initialize memory: Not enough memory resources are available to complete this operation”
    But I wonder I have 87gb space free but why it’s shows error and what it’s mean. Please help me to fix this error, Thank you ?

    1. hey! i don’t work here but just wanted to help you out.

      you didn’t provide enough memory to the virtual machine for it to run.

      memory is your RAM, and is different from your storage. go back to step 12 to check out what i’m talking about!

    2. You Must have that much memory. for example I have 8 Gb of RAM so I can give it 3/4 Gb of RAM to run, But if you have 3 Gb of ram then it will not work’

  3. I just don’t like how is look this Windows 10X, Windows it should be Windows and there how I see is a less control for user. Also must to be and multiple Windows and tabs as how is it now.

  4. FYI: Hyper-V is also available on Windows 8.1 Pro 64-bit.
    I got it working just fine.
    Is there a way to rip iso from vhdx?

    1. Yes I Daily Drive Windows 8.1 Pro and I am very happy to hear that Windows 10X works There

      Answering ur question : no because the vhdx structure is different from iso

    2. The contents of the VHDX file is the installed one, nobody can get the official installer from only the installed files.

  5. Thank you for making this tutorial – I just have one thing to say, which is about the dropped support for Win32 apps. If you head to Update & Security > For developers and enable Developer Mode, you can see that there is an option for Win32 development, so I am guessing that there is a way you can run Win32 apps on Windows 10X, but Microsoft disabled it by default to probably keep it as a light OS.

    Also I was able to use it on an AMD processor, so I’m considering myself lucky.

  6. First of all, thank you for making this step-by-step guide

    Second of all, I am happening to be using an AMD GPU (AMD Radeon HD 5000 Series), and I was able to run Windows 10X without disabling the GPU with no major issues (apart from the time-to-time short period input lag), so maybe there is a small chance that 10X can run on AMD GPUs?

    Either way, thanks for the guide – I really appreciate it.

    1. You need Windows 10 Pro (not home) to get HyperV. If you don’t have it, upgrade to pro or find a way to get HyperV on home.

    1. When I start the Virtual Machine connection it’s shows this error: “Not enough memory in the system to start the Virtual machine Windows 10X.”
      “Could not initialize memory: Not enough memory resources are available to complete this operation”
      But I wonder I have 87gb space free but why it’s shows error and what it’s mean. Please help me to fix this error, Thank you ?

      1. The 87GB free you’re referring to is the disk’s remaining space, but when Hyper-V displays the “Not enough memory in the system to start the Virtual machine Windows 10X.” error, the “memory” it’s referring to is your RAM.

        The only fix I can think of is by closing any running tasks that are taking up a substantial amount of your RAM. You can do this by holding down Ctrl + Shift + Esc (opens Task Manager) and end any running tasks that you don’t need by right-clicking on the task’s entry and selecting “End task”. Be wary though as some tasks cannot be closed like “Antimalware Service Executable” for instance as they’re an essential part of your system, in this case “Antimalware Service Executable” is the task which Windows Defender depends on to keep your PC free from any threats as such.

        You’ll know if you’ve ended enough tasks if the RAM that has been freed up matches or exceeds the amount of RAM you’ve allocated. In my case, I was able to get Windows 10X up and running with 2GB of my 6GB of RAM.

        Hopefully this solves your issue!
