Product Key isn't working RRS feed

  • Question

  • Ok so before, my Win 7 Ultimate was working fine and it was considered "genuine".

    But then my laptop got a virus and I had to wipe everything and reinstall.

    I'm using the same product key but now, the stupid thing keeps saying my software isn't freaking "genuine" anymore.

    I'm 100% sure it's genuine, I've got the sticker, the cd, everything and it worked before, but windows isn't accepting my product key anymore.

    What am I supposed to do?

  • Hi,


    First, please check if you have activated the system. If not, please refer to the following link to activate it:


    How to activate Windows Vista


    If you have activated the system, please let me know if you have visited the MGA Diagnostic webpage located at the address below and click on the “Start Diagnostics” button and follow the instructions:




    On the above website, we can test some system settings and confirm that there are no Internet Explorer (IE) settings or other factors blocking the validation process. If it was successful all results should display “Passed”, if any of them failed please follow the directions to attempt repair. Please let us know which test failed and the results of the troubleshooting performed as suggested by the web site.


    If you have accessed the site but the validation issue persists, I suggest we try the following steps to test this issue:


    Step 1: Test the issue in Clean Boot.


    After that, please restart the computer and validate the system again to check if the issue still persists.


    Step 2: Run the MGA Diagnostic Tool to troubleshoot this issue
    1. Please open Internet Explorer and visit the following link to download the MGA Diagnostic Tool:




    2. Save the "MGADiag.exe" file to the "Desktop", and then double click on the file to run the tool.
    3. Click the “Continue” button.
    4. Under the “Windows” tab, click the "Resolve" button if it is highlighted.
    5. Restart the computer and visit the following website to validate Windows again.




    Additionally, you may contact our Windows Genuine Advantage support via the following link, which is free of charge:
