WhyNotWin11 is a Windows 11 upgrade readiness utility that shows you which components of your PC are ready or not ready for Windows 11. It shows an overview of your system architecture and highlights the components, disk partitions, and other items that may prevent it from being upgraded to Windows 11. While the utility is intended mainly for Windows 10 systems, it will run on earlier versions as well.

App Notes
