* Microsoft has recently made some changes with a WGA update for Windows XP Professional as well that result in not just a pop-up balloon, but instead the wallpaper changes to black, and there will be a translucent notice in the lower right-hand section of the screen that the user cannot get rid of. However, they can interact with things placed behind it still. There will also be a notification at the login screen. The user can change their desktop wallpaper to whatever they want, but the notifications will remain, and every 60 minutes it will revert back to the black screen.
