WhyNotWin11 is a Windows utility that checks a PC's hardware and system configuration against Windows 11 requirements and reports which criteria fail. It is written in AutoIt and distributed as a standalone executable, also supporting Windows 11 update eligibility checks.
Use cases
- check if my pc can run windows 11
- find out why my computer is not windows 11 compatible
- verify tpm and cpu requirements for windows 11 upgrade
- diagnose windows 11 hardware compatibility before upgrading
- check windows 11 update eligibility
- run a windows 11 readiness check from winpe
When to choose
- you want a free, open-source alternative to Microsoft's PC Health Check with detailed per-requirement results
- you need to check compatibility on minimal systems like WinPE or Windows 8.1
- you want to see exactly which Windows 11 requirement your hardware fails
When to avoid
- you need a tool for Linux or macOS - it is Windows-only (Wine support is limited to old versions)
- you want an enterprise fleet-wide compliance scanner rather than a per-PC diagnostic
- you need guaranteed support on unsupported systems - the /force parameter is unsupported
