vista start menu

I have used Vista several times of the course of the last 1 and a half years and always the same thing The start menu gets messed up. I create folders tuneup, games, media etc... to keep things organised I reinstalled vista last week and last night I download winamp for shoutcast and went to launch something and saw a folder in the menu called programs it was a copy of everthing in my start menu? I deleted it and now there is nothing in the all programs menu I really like vista and contrary to what some (experts) say my games play much smoother in vista than XP. I really dont want to use xp but If I have to redo my start shorcuts everyday I will probably go back. Does anyone have any idea on what my be causing this
