The recent mandatory Windows 10 KB5058379 update, released to address critical security vulnerabilities, has inadvertently caused some devices to boot unexpectedly into BitLocker recovery mode after installation. This issue is notably affecting devices from leading manufacturers such as Lenovo, Dell, and HP.
Impacts of the KB5058379 Update
The KB5058379 cumulative update includes crucial security patches, addressing five zero-day vulnerabilities actively exploited in the wild. However, this essential update has led users to face the inconvenience of BitLocker recovery prompts upon restarting their computers, a problem acknowledged by Microsoft.
- Users report that directly after the update is applied and the system rebooted, instead of a smooth startup, they are greeted by the BitLocker recovery screen.
- Secure Boot and other virtualization technologies are identified as potential triggers for this phenomenon, and disabling them appears to be an interim solution for some users.
Microsoft is aware of the disruption caused and is actively working on a resolution to restore normal functionality. In the meantime, they recommend disabling Secure Boot as a potential temporary fix. It is hoped that a more permanent solution will be rolled out shortly, restoring user confidence and system reliability.
As Microsoft progresses towards a resolution, the tech community remains attentive, anticipating an update that will resolve these recovery mode incidents without compromising the critical security improvements the KB5058379 update is meant to deliver.

Recommended Actions
For those affected by the BitLocker issue post-update, Microsoft has advised a series of actions:
- Consider disabling Secure Boot from the system BIOS settings.
- Review and possibly disable certain virtualization settings that might interfere with the update process.
While mitigations are in place, users are urged to proceed cautiously and ensure they have up-to-date backups of critical data before making system changes or disabling security features.
The situation exemplifies the complexities involved in delivering security updates across a diverse hardware landscape, where seemingly routine patch deployments can result in unexpected compatibility challenges.
