|So, is the object to get an answer from MS rather than deleting the files yourself?|
If so then good luck with your crusade but I doubt anyone here will join because we'd be doing it day and night on all topics.
If you want to find a way to delete the files then we can try to help. I've never been defeated yet and other helpers might join this thread.
If you mean that you are always getting this happening, then I accept it is a totally different ball game, although someone here might still know a way around it. I've never run into it on my Vista.
Always pop back and let us know the outcome - thanks
