Update KB5003209 (Monthly Rollup for Windows 8.1 and Windows Server 2012 R2) includes enhancements and fixes, and addresses the following issues.
Security updates to Windows App Platform and Frameworks, Windows Silicon Platform, and Microsoft Scripting Engine.
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.
