Hide ▲

Microsoft's October 2025 Windows security updates are causing some Intel devices to enter BitLocker recovery during startup or restart, briefly blocking normal access. The issue affects Windows 11 24H2, Windows 11 25H2, and Windows 10 22H2. Users may need to enter the recovery key once before the device boots normally again, and administrators can use Known Issue Rollback (KIR) as a mitigation.
