Windows 11 upgrade checker tool for system requirements from windows 10?

If PC Health Check says your PC isn't supported but doesn't give clear reasons, use these built-in Windows tools for a detailed diagnosis.

1. Check TPM (Trusted Platform Module)

This is the most common stumbling block.

Press Win + R to open the Run dialog.

Type tpm.msc and press Enter. This opens the TPM Management console.

Look under Status. It should say: "The TPM is ready for use."

Check the TPM Manufacturer Information section to confirm the Specification Version is 2.0.

2. Check Secure Boot & CPU Generation

Press Win + R to open the Run dialog.

Type msinfo32 and press Enter. This opens the System Information panel.

Look for the following lines:

Secure Boot State: Should say "On".

BIOS Mode: Should say "UEFI".

Processor: Check the model name (e.g., "Intel(R) Core(TM) i7-6700K"). You can then google this model to see if it's 8th Gen or newer.

This is the official Windows 11 upgrade checker tool provided by Microsoft.
