Hi, I am giving a XP Home OEM PC to a friend. It has been lying idle for months so I had to put a new MoBo battery in. It still has original HDD and hardware etc and activated in my name. I reformatted the drive and installed the OS in my friends name. Can I reactivate it at my BB connection or up at his house. I know I will have to phone Micro$oft to do this. Also if/when activated can I install M$ updates as he is on dial-up.
