windows7 validation RRS feed

  • Question

  • I havesometime ago acquired Windows 7 and managed to install it on my personal
    computer. I later uninstalled it and in my attempt to re-install it again,
    my product key was no longer valid.

    Please advise on how I can solve this issue.

  • If you have not done so yet, try reactivating by phone.

    If online activation fails:
    Call Microsoft Using Manual Phone Activation
    Note: If it’s an Upgrade - if you are still installing Windows and at the Enter Your Product Key page, do not enter your key and uncheck "Automatically Activate When Online" then click OK/Next to finish the installation.

    If you have trouble activating Windows 7 you can call Microsoft to activate by doing the following:
    1. With Windows running click Start, then in the Search box type: slui.exe 4
    2. Press Enter on your Keyboard
    3. Select your Country.
    4. Select the Phone Activation option, then call the number given and hold for a real person.

    If you're still unable to activate:
    1) Download and run the Microsoft Genuine Diagnostics Tool:

    2) Copy and paste your results in the Windows 7 Genuine Advantage Validation Issues Forum along with some info regarding where you bought your copy of Windows:
