The installed operating system seems to be XP Home edition - which explains why your XP Pro key edition will not work.

You need to reinstall with the appropriate Pro OEM media, using the key for Pro.

  • I installed Vista in a Virtualbox VM and the product key does not work, how to fix this? I use the same product key supplied with the computer originally.

    I bought a Dell Precision T3400 of Dell Financial Services and it came with Vista Business installed.  I installed a new hard drive and installed Vista in a Virtualbox VM by using the recovery disk that came with the computer, and the product key does not work for activation.  I get a message that says I need to activate Windows, but he says that the product key is not valid.  How can I fix it?

    Thank you

    If you have reinstalled the OEM of Vista Business copy on the new hard drive, as Bill says you can't also use it in a virtual machine.

    You can only reuse your OEM of Vista professional copy if it is no longer used on the computer. Do you have what operating system installed on the new hard drive? It was an upgrade copy or complete the license?

    If you used a license to upgrade to another edition of Windows to replace your copy of company then Vista Business license is still in use (for upgrade) and you cannot reuse it in your virtual machine.

    However if you replaced Vista business with a copy of the full license of another edition then you are able to use the OEM copy in a virtual machine, but only on the same computer. You must use the product key from COA to the label on the computer. The product key is put in the copy OEM cannot find the SLIC table on the host motherboard. You must use the phone activation from within the virtual machine. Click on start in Vista Business and typing "slui 4. Do not meet the audio guests until it asks you if you want to speak to an agent. Explain that you have completely replaced the OEM copy with a copy of the full license of the new windows and now want to use the OEM copy in a virtual machine on the same computer. Agent will then give you the activation string. Remember that the virtual machine is not transferable to any other computer.

  • After update Win OS is not genuine and my product key is not valid

    Hello

    I have a Toshiba EA60 - 156 computer equium laptop using the preinstalled software. Suddenly after running auto-updates to update, windows think now its not authentic and my product key is not valid. After trying to check online, I was told to contact Toshiba after checking the key online. Online my copy is authentic, but windows still considers that it is not.

    What should I do?

    Iain

    I raise reading Microsoft license Validation could be responsible for such messages.
    This tool distributed by Microsoft through its Windows Update platform for some time considered the factory image Toshiba installed an illegal copy of Windows XP.

    I think that to avoid popping up this message, you must remove this License validation tool.
    I think that the idea is also to contact the service partner in your country. Maybe they have detailed information on this issue

  • Re-install Windows 8 pro on PC, how many times before that the product key is not valid?

    Due to problems with Windows Update, and more specifically by using the 8.1 free update, I had some problems and have re-isntalled twice now on this PC.

    You install previous motherboard no re-day after the first installation.

    First install on the replacement motherboard activated via telephone due to the new material.

    2 more reinstall without a phone on the same PC.

    The general consensus is that, once you get to the installation of 5th Activation of the phone is necessary.

    How many times before that the product key is not valid?

    I only ask that the errors are related to data that is not stored on my PC.  and given that Windows 8 is nowhere near the performance and stabilty before I used the App store update I have to reinstall until it's resolved.

    Required to reactivate by phone after the 5th reinstalled only happen based on the license.

    If you make significant changes with a license pre-installed as a motherboard, then you will not be able to use the phone or Internet activation.

    My laptop is with pre installed Windows7 professional edition, and I have a new product key WAU (Home premium-> NEC) in hand. When I tried this product key in the Express Windows upgrade process, I received a message "product key is not valid.
