Vista Tweaker is a great app! I did come across one problem. I used the remove WMP contect menu items and after that I could no longer open media files from Win Explorer. Open with worked ok. I tried re-associating the file types and mo go. Luckily I found a solution to fix (undo) the tweaks. Start > Run> regsvr32 wmpshell.dll I'm sure other people have already requested the ability to undo/restore tweaks. Anyway, thought I would post this in case someone else experiences this problem.
