KB5005076 (Monthly Rollup) for Windows 8.1/Server 2012 R2
Update KB5005076 (Monthly Rollup for Windows 8.1 and Windows Server 2012 R2) contains improvements and fixes, and addresses the following issues.
- Changes the default privilege requirement for installing drivers when using Point and Print. After installing this update, you must have administrative privileges to install drivers. If you use Point and Print, see KB5005652, Point and Print Default Behavior Change, and CVE-2021-34481 for more information.
- Addresses an issue in which Smart Card Authentication (PIV) fails on non-RFC compliant printers and scanners requiring smartcard authentication. For more information, see KB5005391.
- This update also contains miscellaneous security improvements to internal OS functionality.
This update is automatically downloaded and installed by Windows Update, but is also available from the Microsoft Update Catalog and via WSUS. If installing manually, the latest Servicing Stack Update (SSU KB5001403) must be installed beforehand – although this SSU cannot be uninstalled.
Microsoft is aware of the following issue related to the update: Certain operations, such as renaming, that you perform for files or folders on a Cluster Shared Volume (CSV) may fail with the error "STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)". This occurs when you perform the operation on a CSV owner node from a process that does not have administrator privileges. The KB article suggests a workaround to fix this. In addition, there is another issue with the Elastic File System (EFS) API (as with all Windows updates). Details can be found in the KB article.
