Getting restrictions on your access on Windows is frustrating. However, our users will see that the error “Access Control Entry is Corrupt” appears in a yellow field after clicking OK to save the changes, which means that your access to a file or folder is not allowed.

One of the reasons this happens is that the system file is corrupted. Sometimes, when one or more system files have been corrupted and prevent the change from being forced, the error “Access control entry is corrupt” occurs. Another reason is that your file has a generic owner. No owner is being asked, so Windows will report an error. Finally, your Universal Windows Platform application interferes with your permissions.
