I have created a tool that helps you diagnose any issues you may come across when preparing or migrating/upgrading to Windows 11.
This app outputs the key Specs of your device and runs them against the minimum Windows11 requirements.
I have also added quick access buttons for TPM Management, System info, launching DirectX Diag and Windows11 Supported Processor lists.
