Windows 11 Hardware Requirements Not Met

Error code: 0x803FA067 Platform: Windows 11 Updated: 2026-07-17

What This Error Means

Windows 11 refused activation because your hardware does not meet the minimum requirements — most commonly TPM 2.0, Secure Boot, or a supported CPU generation. This error appears during in-place upgrades and clean installs alike.

It is separate from licensing: even a valid key cannot activate Windows 11 on hardware Microsoft classifies as incompatible, unless you use official workaround builds or stay on Windows 10.

How to Fix It

  1. Check TPM: Win+R → tpm.msc — ensure TPM 2.0 is present and enabled in BIOS.
  2. Enable Secure Boot in UEFI/BIOS settings.
  3. Verify CPU compatibility on Microsoft's Windows 11 supported processors list.
  4. Use the PC Health Check app to identify which requirement fails.
  5. If hardware cannot be upgraded, consider staying on Windows 10 (supported until October 2025 for Home/Pro) or purchasing a compatible device.
