Someone can help me understand the way XP licensing works? I have a retail copy of XP Pro. Up to Windows2000, Microsoft allowed the use of a single copy of Windows on both a desktop and a notebook (assuming that when you work on a notebook you are away from the desktop). Now I would like to buy a desktop PC to work more comfortably when I'm home: I want to build the machine by myself to spare some money, I'd like to use my XP copy as I did some years ago with the 2000 Pro. I hear contraddictions about XP Pro these days... some people say nothing has changed, others say the desktop/notebook story is not permitted anymore. Actually XP eula states you can use the system on one single workstation but one may say a notebook is not a workstation... When I call people at WPA, they say they're not sure and I should contact blah blah blah... What do you know for sure about this? Any of you in my same situation?..
