Your computer has what’s known as an Access Control List (ACL). Its job is to tell Windows the resources, such as files and folders, users can access on your computer. If something corrupts the ACL, you can run into the “access control entry is corrupt” error when trying to access certain resources on Windows.

We’re going to show you how to get rid of the “access control entry is corrupt” error on your Windows computer.

1. Perform an SFC or CHKDSK Scan

Running an SFC scan can fix the error by fixing any corrupt system files associated with the proper functioning of the ACL. If the files are missing, a DISM scan will replace them using a cached Windows system image file. If these two scans don’t work, the problem could be related to hard disk errors, which you can fix with a CHKDSK scan.

The above-mentioned tools arebuilt into Windows to help repair corrupt or damaged files, and you should familiarize yourself with how and when to use them.

2. Close All Universal Windows Platform (UWP) Apps

Sometimes, UWP apps can lock resources when they’re running in their sand-boxed environment. They’re not supposed to, but when they do, you can get the “access control entry is corrupt” error message. To fix this, close the UWP app you suspect is the culprit and then update or reinstall it.

3. Change Ownership of the Affected File or Folder

Taking ownership of a file or folder can sometimes resolve the “access control entry is corrupt” error. To do that, follow the steps below:

Now that you’ve changed ownership, try accessing the file or folder again and see if the error still shows up.

4. Try Accessing the File or Folder From a Different User Account

Sometimes, the error pops up because your user account is corrupt, meaning that all the fixes above will most likely fail. What you’re able to do iscreate another user account on Windows for troubleshooting purposes.

Try to access the file or folder (provided it is in a publicly available directory), and if the error doesn’t pop up, you may migrate the necessary files from the old account to the new one.

Then,factory reset your Windows PC, and that should get rid of the “access control entry is corrupt” error.
