Every tried to delete a network folder only to find moronic windows has placed a file there and locked it so preventing you from deleting it?

Go to "User configuration" -> "Administrative Templates" -> "Windows Components" -> "Windows Explorer". c. Turns off the caching of thumbnails in hidden thumbs.db files. Sorted.
