How much upgrading does XP let you do after Activation?

  1. Can I change my moniter? Add more RAM? Add a DVD-R - or change the order of my current devics on the motherboard?

    I have XP Home.

    Many thanks!

    Since it's your hardware, I think you can change anything you want in your system. But anyways you will have to re-activate your product @ MS.

    The activation code includes the following hardware details (at least):

    volume serial number of system volume

    network adapter MAC address

    CD-ROM drive hardware identification string

    CPU serial number

    harddrive hardware identification string

    SCSI host adapter hardware identification string

    IDE controller hardware identification string

    CPU model

    RAM size

    A bit that states whether the system is dockable or not (a laptop)

    Naturally, if you don't have some of these things, they won't be included, but they might be added to it if you upgrade, I'm not sure. XP creates a code using these values (in addition to some other things), and when you change your hardware, it compares the value to the one used at the time of activation. If more than three of these ten bitfields are changed, re-activation is required.

    I can't remember the last time I've had to activate XP since I installed it. In that time though I have changed Graphics card, added a CD-RW, & used several Soundcards without it asking to be re-activated.
    Changing device orders shouldn't make any different to it at all.
