I now own a WIN 7 Home Premium (Compaq) it is an OEM
The WINXP was sent to a schoolteacher and the DELL had contained 4GB and a 160 GB HDD.
The Compaq, I have burned HP_Recovery(D) in the event something goes awry. There are two numbers for it. I have both on Belarc advisor. It says that if I update from Home Premium That can be changed. Darrell
