Windows 11 says TPM is missing after a BIOS update
The PC passed the Windows 11 check before, but after a BIOS update Windows says TPM 2.0 is missing.
Assume a firmware setting changed before assuming the hardware failed. On AMD boards the setting is usually called fTPM. On Intel systems it is often PTT or Intel Platform Trust Technology.
The safe path is to check what Windows sees first, then change only the TPM/fTPM/PTT setting if the firmware screen clearly shows it. Do not change boot mode, disk mode, Secure Boot, or BitLocker settings while guessing.
We need enough detail to separate a reset firmware setting from a real compatibility issue.
Attach only the parts that help diagnose the problem. Hide passwords, serial numbers, account names, recovery keys, and public IPs unless we explicitly ask for one.
What to attach: tpm.msc Status, msinfo32 with BIOS Mode and Secure Boot State, the PC or motherboard model, and a firmware photo only if it safely shows the TPM/fTPM/PTT line without service tags or passwords.
Start with what Windows sees. Press Win + R, type tpm.msc, and write down the Status message. Then run msinfo32 and check BIOS Mode. If it says Legacy, stop before changing boot mode or converting disks.
- Open
tpm.msc. If it says a compatible TPM is ready and Specification Version is 2.0, the problem is likely an old readiness result or a different requirement. - If
tpm.mscsays compatible TPM cannot be found, restart into firmware and look only for TPM/fTPM/PTT. Do not change boot mode, disk mode, or Secure Boot yet. - Enable only the TPM/fTPM/PTT setting if you clearly find it, save, boot Windows, and check
tpm.mscagain.
Do not do this yet: Do not clear TPM, reinstall Windows, convert MBR/GPT, switch storage mode, or disable BitLocker recovery protection while guessing.
Stop and add details if BitLocker asks for a recovery key, you cannot identify the motherboard or laptop model, the firmware has several TPM-like options, or tpm.msc still says TPM is missing after enabling fTPM/PTT.
