What does NTSTATUS 0xC0290007 (STATUS_TPM_DISABLED) mean?

STATUS_TPM_DISABLED

Disabled TPM state and platform configuration

STATUS_TPM_DISABLED indicates that the requested operation reached a TPM state in which use of the module is disabled. It is not a password or authorization error, and repeating the same higher-level operation normally cannot enable the TPM.

For Windows troubleshooting, distinguish a disabled TPM from an unavailable driver or a TPM that is enabled but not ready for provisioning. Firmware setup, enterprise device policy and a pending physical-presence action can affect the effective state. The correct evidence is the TPM status and the firmware configuration, not only the application message.

What to establish before changing state

• Use Get-Tpm to separate presence, enabled state and readiness.
• Check whether a firmware change or PPI request is waiting for confirmation during boot.
• Do not clear the TPM merely to change an enabled/disabled setting; first identify the platform control that owns that state.
