Microsoft warns that October 2025 security updates (KB5066835 for Windows 11 25H2/24H2 and KB5066791 for Windows 10 22H2) may trigger a one-time BitLocker recovery prompt on some Intel devices with Connected Standby; while no data loss is reported and Windows Server is unaffected, users should ensure they have BitLocker recovery keys available, and organizations can use a Known Issue Rollback (KIR) and monitor Release Health for ongoing guidance.
