Putting an end to the incessant rumors, Microsoft finally unveiled its next-gen desktop operating system – Windows 11. This version of Windows brings a completely new UI, a centered taskbar, redesigned Start Menu, Android app support, and more. While we expected the company to roll out the preview build right after the event, Microsoft had different plans.
The Redmond giant released Windows 11 official system requirements and a PC Health Check tool to let users check if they will get the Windows 11 update or not. And well, if you have used the PC Health Check app, you know it’s barebones and buggy. It doesn’t explain why you are seeing the “This PC Can’t Run Windows 11” error and how to fix it. Worry not! A free, open-source app called WhyNotWin11 is here to your rescue and will tell you exactly why your PC can’t upgrade to Windows 11. So without any further ado, let’s dive in.

Before we explain how to download and use this third-party app to check why your PC can’t run Windows 11, let’s quickly take a look at the categories, including SecureBoot, TPM, and compatible CPU, that the app checks for on your computer.

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.
Note: If you are using Google Chrome or any other browser on Windows 10, the app will download right away. But, Microsoft Defender SmartScreen will block the app from running when you open the EXE file. You will see a “Windows protected your PC” message, where you need to tap on “More info -> Run anyway” to use the WhyNotWin11 tool.
3. As for Edge users, hover on the error message in the “Downloads” section and click the three-dots menu icon. Then, click on “Keep” from the pop-up menu.
4. 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.
5. 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:
