Iain's right, you can't tell just by looking at a PC. Mine came with a CD and the COA had been attached to the PC by the local shop who built it. If you bought the PC, you'd soon find out whether or not Windows was genuine when you download the Windows Genuine Advantage Notification update, but it might be too late by then! If it wasn't genuine, you'd be bombarded by nagging balloons, pop-ups etc until you got a genuine version of Windows, so be very careful about what you buy. Madeline.
