A recent Windows update from Microsoft has caused some PCs to demand a BitLocker recovery key at startup. The issue affects Windows 10, Windows 11, and server versions. Microsoft confirmed the problem and provided temporary fixes but advises users to check before installing the update.
The error occurs due to a specific security configuration in the update. Users report seeing a prompt for the recovery key without prior changes to their system. This forces an interruption in normal operations, especially for businesses relying on uninterrupted access.
Microsoft listed affected configurations in a support document. The company stated that PCs with BitLocker encryption enabled and certain security policies are at risk. The update does not break encryption but triggers an unexpected recovery process.
Temporary workarounds include disabling the problematic policy or using the recovery key. Microsoft warns that skipping the update is not recommended for security reasons. Users should back up data before proceeding with fixes.
The company is working on a permanent solution. In the meantime, users must follow the provided steps carefully to avoid data loss.
