STATUS_TPM_INSTALL_DISABLED
Legacy owner installation and modern provisioning
STATUS_TPM_INSTALL_DISABLED concerns the legacy TPM 1.2 ability to install an owner. It does not simply say that a Windows account lacks administrator rights. The older owner model is part of TPM 1.2 terminology and does not map one-to-one to every TPM 2.0 provisioning workflow.
When this appears on a current Windows system, establish whether a legacy application, compatibility layer, management tool or device firmware path issued the request. Windows TPM provisioning uses platform and OS management interfaces; it is unsafe to assume that changing an old owner-related flag will repair a BitLocker, Hello or attestation issue.
What to establish before changing state
- Identify whether the device is TPM 1.2 or TPM 2.0 and which software invoked the owner-installation path.
- Record current provisioning and physical-presence requirements rather than editing owner material manually.
- Use documented management workflows for the deployed Windows version and device-management policy.
