If you have been a victim of software piracy and do not have a genuine licence for the windows XP operating system you use then Microsoft will catch you red handed if you try to update your system using microsoft support and download site.
you will be barred from changing your wallpaper and your desktop will be all Black!! a small notifying balloon will popup and stay forever in your lower right bottom and will continue to annoy you till you validate your genuine licence key. Nothing less than a nightmare when your PC tries to bully you!!
