Windows update triggers BitLocker recovery prompt for many PCs

Microsoft acknowledged that recent Windows updates are forcing certain computers into BitLocker recovery screens without warning, affecting devices with Intel processors across Windows 11 versions 24H2 and 25H2, along with some Windows 10 22H2 installations. The encryption system typically requests recovery credentials only after detecting significant hardware modifications or BIOS resets, but the latest patches trigger protection protocols despite no actual system changes occurring.

Updates KB5066835 and KB5066791 appear responsible for the malfunction, which Microsoft attributes to conflicts with Connected Standby power management features that maintain network connectivity during sleep mode. The technology enables laptops to sync messages or play audio without full activation, yet Intel chip handling of reduced power states may be generating false security alerts that mistakenly activate data protection measures.

A correction will be distributed through automatic updates in stages after completion. Users should locate their BitLocker keys through Microsoft accounts, Azure Active Directory, or printed backups to restore normal startup if recovery prompts appear. Azure virtual desktop environments running Windows 11 24H2 have experienced similar lockouts, creating access problems for enterprise-encrypted machines. Systems remain functional once users input valid credentials.
