How to Install Windows 11 on Unsupported PCs?

Posted by

Finally, Windows 11 was released by Microsoft on 4 Oct 2021; however, it was scheduled to final launch on 5 Oct 2011. Then, I tried to update Windows 10 to Windows 11 on my Intel-based MacBook Air, and finally, I was surprised. It simply refuses to install on our computer. Here is the error screenshot:-

The error was simple, “This PC doesn’t currently meet Windows 11 system requirements.” My PC could not run Windows 11 due to these hardware requirements:-

  • The processor isn’t supported for this version of Windows.
  • The PC must support TPM 2.0.
  • The PC must support Secure Boot.

Then, I decided to try my old method, bypassing TPM 2.0 and Secure Boot. And then, Windows 11 setup started without any error.

In this gearupwindows article, we will guide you with full details to quickly bypass these errors and install Windows 11 on an unsupported computer, even on an Intel-based Apple machine.

How to Install Windows 11 on Unsupported PCs?

Step 1. First, download a Windows 11 ISO file from the Microsoft server (The final version of Windows 11 ISO file size is around 5.2GB).

Step 2. When downloading is completed, extract its contents in a folder using WinRAR or other software. To do that, right-click on the ISO file and select the “Extract to” option.

Step 3. When ISO file contents are imported into the folder, open the “Sources” folder and delete the “appraiserres.dll.” This file is 192KB in size that is responsible for checking Windows 11 requirements.

Step 4. Then, double-click on the “setup” file from Windows 11 folder to start installing it.

Step 5. In the “Windows 11 setup” window, first, uncheck the option, “I want to help make the installation better.” Then click the link, “Change how Setup downloads updates.”

Step 6. Next, select the Not right now option and then click the Next button.

Step 7. When you see, “Applicable notices and license terms” header, click the Accept button at the bottom.

Step 8. In the next window, leave the options “Install Windows 11” and “Keep personal files and apps” checked. Then click the Install button. If you want to clean install, uncheck both options. It will erase the Windows 10 drive (Usually “C” drive).

That’s it!. Now, Windows will prepare itself, and your computer will be updated from Windows 10 to Windows 11. It may take a while, depending upon the speed of your PC.

  1. I have all the requirements supported except for my i3 6th gen processor ,can i upgrade using your methods and can i get windows updates later?

  2. Dear Jack,

    We tested it on an Intel-based MacBook, and we got success, and there is no issue yet. Further, we also received the update that we downloaded and installed without any problems. Microsoft only says unsupported PC may not get an update, but they are not stopping it, at least for now. So, you can install it on your computer without any issues. Good luck!

  3. I am installing Windows 11 right now on a Lenovo Tiny M73 with 4GB RAM and an i3 processor. Looking good so far. Also installing on an older Samsung laptop with an i3 processor and 4GB RAM. Looking good there, too.

  5. It worked. A clean way of upgrading unsupported PC / Laptop to windows 11. Thanks a lot. It saved the cost buying new windows 11 Laptop / PC. My PC config: Asus Z170AR motherboard, Intel i7 6700K CPU. Both are not in the Microsoft’s list of supported hardwares.

  6. I have licensed windows 10 if I upgrade to windows 11 with this method will it still stay licensed?

  7. Cool you deleted the file which checks the requirement.🤣🤣… smoothly installed on i3 10thgen Lenovo.

  8. Hello ,I have Asus vivobook x540ba with 4 gb ram and AMD A9(dual core) processor, all things supports except processor, After install will it run smoothly on 4 gb and with this processor?
    (Normal ram usage after bootup ~50 %, is 4 gb is enough?)

  9. Previously I tried different methods like deleting a file, copying some files to Windows 10, and even changing the registry but everything it failed at the initial stage. This time I tried following the same and it crossed the compatibility issue. Hope this should work now.

  10. I have intel Pentium G630 2.7ghz processor and 4gb ram is it good for my pc to install windows 11 or it will make my pc slower than windows 10

  11. There is a reason I did not install Windows 11 on my unsupported PC, if your BIOS wreaks havoc, it’s your cpu’s fate.

  12. Hello Pammi!
    I just downloaded the ISO file from Microsoft’s site.
    I deleted the appraiserres.dll file. Then another error and it exits.
    This: We are unable to determine compatibility on this machine.
    Could you send me an older ISO file? Because since then Microsoft has also improved this.
