When I try to delete files from my desktop or copy files to it I'm told that I don't have permission to do so, but I'm the administrator. It's Windows 7. I've seen something about anti-virus protection maybe being an issue and I have McAfee installed.

Seriously? You want him to take ownership of every file on the C drive? What about files and folders which have ACLs containing ACEs that reference Creator Owner? All of a sudden those ACEs refer to you instead of the some other user. That could break something. I wouldn't recommend it. – Fran Jul 5 '12 at 0:37
Yeah, @Fran is right. Also, it'll pop-up with a lot of error messages too. Just use that method less globally, i.e. only on certain folders. – imtheman Jul 5 '12 at 7:51
