XP SP2 switches-off a load of drivers by manufacturers names. Happauge WinTV and Norton AV being two rather notables.

BASICALLY don't load SP2 till you read the stories. Bit late I know. One of the reasons I am holding off on XP - the other is the other M$ trick of locking you in, and snooping on your system.

The next business model is software leasing, - if you accept XP you are already giving them the nod. You pay each year and you get updates. Like SP2 - isn't technology wonderful? Well the answer is yes, its the money men who have taken over (long since).
