    Double check and make sure you've checked the "Replace owner on subcontainers and objects" under Change owner, as well as the "Replace all child object permissions entries with inheritable permission entries from this object" so as to cascade your changes to all sub-folders and files.

    That should do it and assuming you've clicked all the appropriate "OK" buttons along the way, and answered in the affirmative when prompted if you wish to continue you should be able to delete the Windows.old folder and end up with this
