Here is the one issue that appears on Windows 10 Initial version after upgrading to KB4503291 cumulative update-

Symptom Solution

While performing certain operations like- renaming of files or folders which are on a Cluster Shared Volume (CSV) may not work and rather fail to display following error message-

“STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”.

This bug primarily arises only if you try to accomplish operations on a CSV owner mode using a process that lacks Administrative privileges.

To solve this Error, you should do the following-

  1. Sign in to your PC as Admin then execute such operations.
