+1 I have used the hacked SFC_OS.dll + registry method to disable WFP before, but all I really want to do is delete those annoying folders that XP puts in the Program Files directory (e.g. "xerox", "MSN Gaming Zone", "Movie Maker", etc). Is there any way to remove these from the list of protected files rather than disabling WFP altogether. And also, does anyone know why the heck those stupid folders are considered protected system folders in the first place? Disable WFP, delete the folders, then re-enable it. Does that work?
