You don't need any Windows 11 compatibility checker tool. Instead, here are the key requirements to check for Windows 11 compatibility:

1. Core Hardware Requirements

Processor: 1 GHz or faster, 64-bit, with 2+ cores — and it must be on Microsoft's supported CPU list (most Intel 8th gen+ and AMD Ryzen 2000+ qualify)

RAM: 4 GB minimum

Storage: 64 GB minimum free space

Graphics: DirectX 12 compatible GPU

Display: 720p, 9" or larger

2. The Big One: TPM 2.0

This is what blocks most older PCs. Windows 11 requires Trusted Platform Module (TPM) version 2.0. To check:

Press Win + R, type tpm.msc, and hit Enter

It will show whether TPM is present and which version

3. Secure Boot

Your PC must support UEFI firmware with Secure Boot. You can check this in your BIOS/UEFI settings, or by searching "System Information" in Windows and looking for BIOS Mode (should say UEFI) and Secure Boot State (should say On or supported).
