Annoyingly, Microsoft's own tool for determining device compatibility -- the PC Health Check app -- wasn't up to par when Microsoft first announced Windows 11 (there were reports it didn't give people enough information about why their devices weren't compatible), so the company temporarily removed the app. But Microsoft's PC Health Check is now back online and in working order. The app will tell you if your computer meets the requirements to run Windows 11 -- and if your PC doesn't, the tool will tell you why and provide links for more support.

Option 2: Try the WhyNotWin11 app to check Windows 11 compatibility
An open-source app called WhyNotWin11 is a good alternative to the PC Health Check app. The Github app, created by a developer not affiliated with Microsoft, has a less friendly interface, but it should give you more information and go into more detail about various potential compatibility issues. Here's more information from TechRadar on how to use it to determine your own device's compatibility with Windows 11.
