Notifications are the things at the top right of the screen by the clock. If you look at their properties, a list is stored of files that have been removed from there in the past. I was annoyed to see an old spyware proggy on the list. Ok so it is none functional, but I wanted to get rid of its history. Download this Visual Basic program to remove notifiaction history if you are fed up with it. It is hard to remove otherwise...Let explorer be turned off for a second...Right click save as..
