How to Use WhyNotWin11 App to Check Why Your PC Can’t Run Windows 11

  1. First, head over to this Github page and download the WhyNotWin11 tool on your existing Windows 10 PC.

  2. Now, since the app is not signed, Microsoft will block the download if you are using the Edge browser. You will see the “WhyNotWin11.exe was blocked because it could harm your device” error. Don’t worry, though. It won’t harm your computer, and you can bypass it.

  3. Next up, on the “This app might harm your device” pop-up menu, click on “Show more” followed by “Keep anyway” to download the tool.

  4. Now, double-click on the WhyNotWin11.exe file to check your PC’s compatibility with Windows 11. The tool takes a couple of minutes to perform the check, so have patience, and wait for the results. As you can see in the image below, my Xiaomi Mi Notebook is eligible for the Windows 11 update:
