Symptom

Workaround

Certain operations, such as rename, that you perform on files or folders that are 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 doesn’t have administrator privilege.

This issue is resolved in KB4550958 for all the releases from January 8, 2019 to April 14, 2020. 

Devices on a domain might be unable to install apps published using a Group Policy Object (GPO). This issue only affects app installations that use .msi files. It does not affect any other installation methods, such as from the Microsoft Store.

This issue is resolved in KB4550958.
