Compatible TPM cannot be found

The TPM management console cannot see a TPM, so the PC fails the Windows 11 TPM 2.0 check.

Why it happens

Windows 11 requires TPM 2.0. When tpm.msc shows "Compatible TPM cannot be found", the TPM is most likely turned off in the PC's UEFI firmware. If a TPM is shown but the specification version is lower than 2.0, the PC does not meet the requirement.

How to fix it

1. 1

   Step 1

   Run tpm.msc, or open Windows Security > Device security, and check whether a security processor is listed and which specification version it has.

2. 2

   Step 2

   Go to Settings > System > Recovery, choose Restart now under Advanced startup, then Troubleshoot > Advanced options > UEFI Firmware Settings.

3. 3

   Step 3

   Find the TPM setting under Advanced, Security or Trusted Computing. It may be called Security Device Support, TPM State, AMD fTPM switch, AMD PSP fTPM, Intel PTT or Intel Platform Trust Technology. Enable it, save and exit.

4. 4

   Step 4

   If you cannot find the setting, check with the PC manufacturer.
