Microsoft is aware of the following problem in connection with this update: Certain operations, such as renaming, that you perform for files or folders on a cluster shared volume (CSV) may fail with the "STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)" error. This occurs if you perform the operation on a CSV owner node from a process that does not have administrator privileges. As a workaround, you can do one of the following:
