Upgrading from Service Pack 2 to pack 3? RRS feed

  • Question

  • I purchased Windows Genuine Advantage Kit for Windows XP Professional  Service Pack 2, and only now realise that it is not compatible with the version I have on my computer (ie.e Service Pack 3).

    Is there a WGA...Service Pack 3 available for purchase through Microsoft?

    If not, what can I do to fix this?

    Am I able to ‘do something’ so that I my version (Service Pack 3) currently on my computer becomes genuine?

    Or is the only option to reinstall a new (lesser) version (Service Pack 2)?.....I hope not…

    Appreciate your feedback.

  • Hello Gabbi,

    What are you experiencing that leads you to think that XP Pro SP3 is "not compatible" with XP Pro SP2?

    You should be able to use the Product Key (PK) that was emailed to you during your WGA purchase to update the installed nongenuine PK with the PK Updater Utility:  http://go.microsoft.com/fwlink/?linkid=45668

    After backing up and offloading valuable data, you should be able to use the WGA supplied CD and the emailed PK to do a clean installation of XP Pro onto your computer.  (This is the recommended procedure.)  After installing XP SP2, simply visit Windows Updates to install SP3.

    The one scenario I can think of where you would encounter a problem is if you are trying to use the WGA supplied XP Pro SP2 CD to do a repair installation of an XP Pro SP3 installation.  In such case you would get a notification that "the operating system you are installing is older than the one already on the computer" or similar.

    If that's the case, you can make a working CD that has SP3 slipstreamed into it to do the repair installation.  Here's a pretty good guide:  http://www.winsupersite.com/xp/sp3_slipstream.asp
