Security updates to Windows Input and Composition, Windows Fundamentals, Windows Hybrid Cloud Networking, Windows Kernel, and Windows Media.
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 KB500140) 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.

Security updates to Windows Input and Composition, Windows Fundamentals, Windows Hybrid Cloud Networking, Windows Kernel, and Windows Media.
The update is distributed via WSUS (but not via Windows Update) or is available from the Microsoft Update Catalog. In case of a manual installation, the latest Servicing Stack Update (SSU) KB5001403 must be installed beforehand. Furthermore, the cumulative security update KB5000800 (from March 2021) for Internet Explorer 11 should be installed. This is because a vulnerability is probably being actively exploited there.
