How To Download And Install Windows 11 Insider Preview On Unsupported Devices Easily

Microsoft launched the most awaited Windows 11 operating system for all the eligible PC owners today via Window Insider Program. The first Windows 11 Insider Preview comes with firmware build number 22000.51; as opposed to the prior leaked Windows ISO v21996.1. See how to download and install Windows 11 Insider Preview on any computer even if the PC Health Check software shows unsupported hardware by Microsoft.

Microsoft has some Windows 11 system requirements for eligibility for a free upgrade. This requires your device to have the newer generation processors like 8th gen or later for Intel, AMD Gen 2 or later, as well as Qualcomm 7 and 8 Series. Most importantly, TPM 2.0 and UEFI with secure boot is a must.

Although the support for Intel processors is constantly updated, it may take very long to get into the Windows 11 dev channel. Here is how to bypass the PC Health Check and get into the Windows Insider Program on unqualified PCs or unsupported hardware.

The following tutorial requires tweaking the Registry to trick Windows into thinking it is supported hardware. This tutorial will help you download and install latest Windows 11 Insider Preview build 10.0.22000.51 easily.

    1. Please open windows explorer, scroll to top left where you could find ‘view’ option. In to the view option please check the ‘hidden file’ box. Go to hard drive C, main page you could find the “C:\$WINDOWS.~BT\Sources” .

  1. Very helpful Mr. Sarang. I got my OS and I thank you very much for the post.

  2. I did not find $WINDOWS.~BT Folder, there is only $WinREAgent Folder, Tell me how to find it

    1. The Folder only appears after you try to install windows 11 , wait for it to fail once , and then surely this folder will be visible. (just make sure you have enabled hidden items in the view section at the top)

  3. Works really well , it puts you into dev channel, however once windows 11 is generally available you will stop getting further updates and will have to roll back to windows 10.
    But otherwise this works really well, Win11 preview build is surprisingly stable

  4. Superb.. 1st step of TPM error successfully washed out and now lets see what will happen next as windows is updating now in update option. Now I would let you know once the window updated successfully but till then anyone tell me that (appraiserres.dll) is from original source and it will not harm my system ?

  5. Thanks for sharing excellent information. Your web-site is very cool. I am impressed by the details that you have on this site. It reveals how nicely you understand this subject. Bookmarked this web page, will come back for extra articles. You, my friend, ROCK! I found just the information I already searched everywhere and simply could not come across.
