Unable to Install Windows 11 – Compatibility Check Fails
Tried moving from Windows 10 to Windows 11 today, but the installer refuses to proceed, saying my computer doesn’t meet the necessary security requirements. The main issue flagged is missing TPM 2.0 support.
This desktop was custom-built a few years back for gaming and content creation, and it still runs modern titles without a problem. I wasn’t aware that TPM settings could block an OS upgrade.
Before I start replacing hardware, I’d like to know if there’s a way to enable or add TPM so the installation can work. Any advice?

If Windows 11 says your PC needs TPM 2.0, try this:
1. Restart your computer and enter BIOS (press Delete, F2, or F10 during startup).
2. Find and enable TPM, Intel PTT, or AMD fTPM.
3. Save and exit BIOS.
4. In Windows, press Windows + R, type tpm.msc, and check if TPM 2.0 is shown.

. Try installing Windows 11 again.If you can’t find TPM in BIOS, your motherboard might not support it, and you may need to add a TPM module or upgrade your motherboard.
