Summary

Hide ▲

Microsoft shipped KB5089549 for Windows 11 25H2 to fix a BitLocker Recovery problem that could trap devices after the April 2026 security updates. The issue involved certain TPM validation settings and could force users to enter a recovery key at restart. Windows 10 and Windows Server are still waiting for a permanent fix, so administrators must rely on temporary policy changes until a broader update arrives. The patch matters because it restores boot access for enterprise-managed systems that were getting stuck in recovery mode.
