It's not the first time Microsoft have launched new products using pop songs.
In 1981 they did a deal with old-timers the Rolling Stones for their song 'Start Me Up' to introduce people to the 'start button' in their Windows software.
The 25 October launch of Windows XP was almost postponed because of the 11 September terrorist attacks.
But it's going ahead with a big party and performances from three more pop acts. Organisers are keeping quiet about Maddy's possible appearance.
