TPM 2.0 is the core hardware requirement to make a machine pc compatible with windows 11. Most older PCs from 2017 to 2019 fail Windows 11 checks due to TPM 1.2 or disabled TPM inside BIOS settings.

How to set up pc compatible with windows 11

1. Check the current TPM version: Press Win+R, type tpm.msc, and press Enter.

2. View the results: Spec 2.0 is ready; 1.2 requires configuration; “TPM missing” indicates it is disabled or no relevant hardware is present.

3. Restart your computer and press the manufacturer-specific hotkey to enter the BIOS:

  • Dell (F2)
  • HP (F10/Esc)
  • Lenovo (F1/F2)
  • ASUS (F2/Del)
  • Acer (F2).

4. Open Security settings: For Intel processors, enable Intel PTT; for AMD processors, enable AMD fTPM; if available, set the option to TPM 2.0.

5. Press F10 to save the BIOS settings and restart the computer.

6. Run PC Health Check again to re-check system compatibility.

Enabling TPM 2.0 resolves the most common hardware issue preventing Windows 11 from installing on older mid-range computers.
