Overview
- Affected releases include Windows 11 24H2 and 25H2 via KB5066835 and Windows 10 22H2 via KB5066791, with Microsoft noting the issue applies across supported client versions.
- Impacted machines may boot to the BitLocker recovery screen and require the recovery key once, after which subsequent restarts should proceed normally.
- Microsoft says the problem primarily hits Intel-based systems that use Connected/Modern Standby, while server operating systems are not affected.
- Administrators can request a Known Issues Rollback from Microsoft Support as a mitigation, and Microsoft says a repair patch is being distributed.
- Users are urged to ensure access to their BitLocker recovery keys, such as via their Microsoft account, because without the key device data may be inaccessible.
