Windows 11 Compatibility Checker is a portable, freeware app that can check to see if your computer is ready for Windows 11 and suggest troubleshooting possibilities.
The best part about Windows 11 Compatibility Checker is the attempts to explain and help you resolve and pending limitations. This is perfect because many people are getting an error that says, This PC can't Run Windows 11 when running the official Microsoft PC Health Check.
Although we expect some of these limitations to change before Windows 11 is released, it may never happen. Microsoft essential eliminates any older (think 3-5 years) computers from upgrading due to hardware limitations. We're hoping the Home build changes this limitation so anyone can run it.
Depending on the error, you may see different results. For example, if your TPM is a problem, you can copy the error to your clipboard. If your processor is the problem, Windows 11 Compatibility Checker can give you a text file of all currently supported chipsets. There's even a simple Requirements button on the main screen to let you see the current Windows 11 requirements.
It's important to run the app as Administrator if you want to try to get suggestions about your problem. The app may crash or return an error otherwise.
We like Windows 11, Compatibility Checker. It's small, free, and portable. Unlike some other apps, Windows 11 Compatibility Checker actually tries to help you solve the problem.
