Your disk is securely encrypted. Precisely! Or is it not?

Microsoft has sent a warning to its customers that some managed Windows environments may receive false messages about problems with BitLocker disk encryption.

According to the Redmond-based company, the issue only affects client platforms, including Windows 11 21H2/22H2, Windows 10 21H2/22H2, and Windows 10 Enterprise LTSC 2019. The problem only occurs in environments where disk encryption is mandatory for the OS and installed non-removable disks.

Intune, a Microsoft cloud-based endpoint management service, is one of the MDM platforms affected by this issue. However, Microsoft did not specify which other MDM applications exhibit these errors with BitLocker.

"Using the FixedDrivesEncryptionType or SystemDrivesEncryptionType policy settings in the BitLocker Configuration Service node in mobile device management applications may incorrectly show error 65000 in the 'Require Device Encryption' setting for some devices in your environment, " the company reported via Windows Health.

Microsoft also clarified that this issue is related to an error in the reporting system and does not affect disk encryption or reporting of other device issues, including other BitLocker issues on devices with an MDM account.

To resolve the issue, administrators can temporarily specify the "not configured" option for the "Force Disk Type Encryption on operating System disks" or "Force Encryption on Non-removable Disks" policies in Microsoft Intune.

The company added that it is actively working to resolve the issue and will provide additional information in an upcoming update.

Earlier this year, Microsoft already fixed a known issue affecting Windows Server Update Services (WSUS) servers upgraded to Windows Server 2022, which caused them to stop sending Windows 11 22H2 updates to enterprise devices. In the same month , another bug was fixed related to video recording and playback errors in applications that use the WVC1 codec on Windows 10 and Windows 11 systems.
