When you go out to Microsoft to get downloads you will be faced with the Windows Genuine Advantage validation check.
This mandatory ActiveX update makes sure that your copy of Windows XP/2000 is genuine before you can access any downloads.
Even a genuine copy of Windows can not register properly. If this happens you’ll need manually enter your registration number. It will be on the manual that came with your XP/2000 disk, or check the side or back of your computer for a sticker.
