    How can windows XP be activated without activation code?

    I updated my PC recently and when I restarted my computer after the update, it asked for an activation code. I gave my product key but an error message saying the key is unauthorized has appeared. I donít have a CD to re-install it. How can I activate my Windows XP Pro?

    By upgrading if you have made some major changes in hardware you will have to retrace it and revalidate the existing XP installation by performing a clean install. If this version of Windows have been running for quite some time this would work better for you. Or if this was a preinstalled version of XP, the possibility of restoration of the Windows could only be done by a set of recovery disks or simply by borrowing a CD of Windows XP Pro and re-installing it. This will help create an updated profile for hardware and on requesting for activation, this would work. This would take some time to get activated.

    Dear friend,

    It seems that either you are using a fake key or someone might have stolen your key and he have used the key.
    If you are key had been stolen, then you must complain to the Microsoft Support Center, immediately and follow the procedure told by them to recover your key.
    It might be possible that your earlier version of Windows XP was registered with a fake key by your vendor, if you have an assembled PC.
    In this case you should contact your vendor for original key.

    If the validation code refuse to get accepted, there must be reasons behind that.

    Do you have original windows installed in your system ?

    Possibly not, and there's nothing much to do and you have to solve the pirated issue with some other means which can't be suggested.
    If you have a Valid Licences Version of Windows with you , then contact www.microsoft.com and talk to them ,
    write in the link, Contact Us, and tell them the problem and thay can issue a valid code.
    But that is possible only if you have purchased a genuine Windows from authorised outlet or over the internet.
