I got this problem. When I try to double click on a folder or a partition in Windows Explorer or My Computer, it doesn't explore/open it, but it start Winamp or JASC Paintshop. I tried to change the action by going to Folder Option>>File Types>>File Folder>>Advanced, I didn't saw the Actions "open" nor "explore". I know that something went wrong there, because I tried to custumize my XP icons, but it wasn't clearly not smart to do that. -_-"
