Treat this document as a focused evidence review: Centralize TPM command and lockout controls with Group Policy. Only the official source and traced locations below supply facts. Confirm applicability before acting.

\n

Source fact:

\n

The official TPM Group Policy settings from Microsoft supports the following bounded statements:

\n\n

These statements are the factual basis for this document. Do not extend them into a broader assurance. Review Windows security controls, protected identities, audit policy, telemetry, exclusions, administrative roles, and response workflows only where the source and recorded environment align.

\n

What the source does not establish

\n

Test command-block policies against firmware, BitLocker, and management workflows before broad enforcement. It does not establish a deployment’s current state, authorize a production change, prove compliance, or show that Active Directory, Windows DNS, certificate trust, time, endpoint management, telemetry pipelines, and security operations are healthy. Documented options are review inputs, not universal mandates.

\n

Applicability questions

\n\n

DSE recommendation:

\n

DSE recommends using the cited source as the evidence anchor for this decision. Start with applicability, then compare the observed state with the cited source. Record the source location, examined part of Windows security controls, protected identities, audit policy, telemetry, exclusions, administrative roles, and response workflows, observed and expected states, owner, and reason for deviation.

\n

If the review warrants change, use a bounded implementation with prerequisites, test population, monitoring, abort criteria, and a rehearsed reversal. Sequence checks for Active Directory, Windows DNS, certificate trust, time, endpoint management, telemetry pipelines, and security operations and sanitize protected material before retention.

\n

Verification and evidence

\n

Keep the source locations Opening overview; Sections: blocked commands; owner authorization; lockout settings adjacent to the sanitized artifacts used for comparison. Prefer policy and feature state, security events, test detections, administrative assignments, exception approvals, and response tickets, with enough identity and timing data for an independent recheck.

\n

Close the review only when the evidence, exception handling, resulting action, and after-state are linked. Schedule a new review after material technical, organizational, incident, or source changes; today’s observation is not a continuing guarantee.
