In my Add/remove programs list, there are 5 entries or programs on the list that cannot be removed. For example, when i click on those entries or programs, the add/remove icon is not there. There is no button i can press to remove it.
Ccleaner has a similar feature...you might try it to remove the unwanted programs. Alternatly you could browse to the programs folder to see if it contains it's own uninstall program.
