Anybody ever had a Windows Product Activation box appear at booting?
 

I'm running Windows XP and am getting a message on booting that Windows Product Activation must activated within a few days. It is an official copy of Windows XP so there is no problem there but I've been running this computer for a couple of years and it has just started showing.

Has anybody else experienced this?

Anybody?

Yeah, I had to call them.

Microsoft has a way to keep their sales going!!! OOF!!!!
