I like to Take Ownership and grant myself Full Control permissions over large
branches of my C drive, like the folder Program Files. Make sure your
actions take effect for this folder and all subfolders and files. Then all
your programs will be under your control. If you want to allow other users
to have access to your programs, also grant them some control and Share
(Properties, Sharing, Advanced Sharing) your Program Files folder. This
tutorial will show you how to do this.
