What's "EXISTS WIN://SYSAPPID" condition in "C:\Program Files\WindowsApps" ACL?

Viewed 5968

I noticed that access rights in C:\Program Files\WindowsApps for Users have a special "condition" applied: EXISTS WIN://SYSAPPID.

ACL condition EXISTS WIN://SYSAPPID

I didn't find anything about ACL conditions or how I could create and utilize such kind of thing.

How can I create and utilize ACL conditions?

I had the same problem, and it wouldn't let me edit that entry to grant access to %USERS% I followed this tutorial. It has 3 workarounds for this problem.

For me, Method 2: Changing the owner to Users worked:

Perhaps the most effective fix for this particular issue is to change the Owner of the folder/file and to take full ownership of it. After doing this, you should be able to edit the permissions without encountering the ‘Access Control Entry is Corrupt‘ error.

  1. Right-click on the folder or file that you’re having issues with and choose Properties from the context menu.
  2. Once you’re inside the Properties screen, select the Security tab, click on the Advanced button associated with Permissions.
  3. Inside the Advanced Security Settings, click on the Change button associated with the Owner.
  4. Inside the Select User or Group, type Users inside the text box, then click on Check Names to verify. If the syntax is replaced correctly, click Ok to save the changes. Then click Apply at the previous window to make the change permanent.
  5. Try to modify the permissions accordingly and see if you still see the error message.
