To put it simply, Windows permissions are complicated.

The ACL model in Windows can often get in an inconsistent state. For example, you can give yourself read/write/execute permissions at the folder level, but this might not percolate downward to individual items in the directory, even if you click the appropriate box in the GUI. I had this happen when my profile got corrupted, and I needed to move files to a new account.

You might need to write a Powershell script to change all of the files individually. Pretty annoying.

Your best bet would be to read up on the built-in utilities called ICACLS.

Edit: the following goes into some of the issues regarding taking ownership of various objects on the Windows system: Link: https://rakhesh.com/powershell/using-get-acl-to-view-and-modify-access-control-lists-part-1/
