Hey, that looks handy. Does it work with agressive spyware?

Interesting, it could be a time saver. I've always removed the file attributes from stuff that wouldn't delete, booting to a command prompt if neccessary.

As a note, it could be dangerous for those who don't understand what they are doing. Windows locks stuff for good reasons, the main one being to prevent trouble.
