Using the FixedDrivesEncryptionType or SystemDrivesEncryptionType policy settings in the BitLocker configuration service provider (CSP) node in mobile device management (MDM) apps might incorrectly show a 65000 error in the "Require Device Encryption" setting for some devices in your environment. Affected environments are those with the “Enforce drive encryption type on operating system drives” or "Enforce drive encryption on fixed drives" policies set to enabled and selecting either "full encryption" or "used space only". Microsoft Intune is affected by this issue but third-party MDMs might also pe affected.

Important This issue is a reporting issue only and does not affect drive encryption or the reporting of other issues on the device, including other BitLocker issues.

This issue is addressed in KB5034204.

When using physical media or disc images (ISO) to install Windows 11, version 23H2 (also referred to as the Windows 11 2023 Update) on a device, Microsoft Narrator might not start.

Narrator is commonly initialized using keyboard commands, such as Ctrl + Windows key + Enter. Although Narrator is present in Windows when the installation process begins, it might open in an unresponsive state when initialized using any method.

Please note this issue does not occur when Windows 11, version 23H2 is installed using Windows Update on a device which is already running Windows 10 or Windows 11. This issue only occurs when physical media or ISOs are used for this installation and Narrator is only affected while the installation process is taking place. It should continue to work as expected once the installation is completed.

This issue is addressed in KB5033375.

Starting December 19, 2023, a new file is available to create an installation media to update to Windows 11, version 23H2. The new media does not encounter this issue and contains the December 2023 security update. It is available for download at the Software Download page for Windows 11 in the section “Download Windows 11 Disk Image (ISO) for x64 devices.” Guidance on installation can also be found at this site.

IT administrators and users also have the option to sign in to their subscription on the Visual Studio Subscriptions portal to download the new media. You can also access the new media on the Volume Licensing Service Center (VLSC) starting December 21, 2023.
