Windows 7 product key is invalid RRS feed

  • Question

  • I bought an OEM Windows 7 disc about 4-6 months ago. Built a new computer and everything installed and activated fine. I then had to reinstall Windows on exactly the same machine. It keeps telling me it's invalid, however it worked previously. It appears that it keeps using the default one, will not register my Windows 7 as valid and will not activate.

    I have tried:

    1) Click Start button.
    2) Type: CMD.exe into the 'Search programs and files' field 
    3) Right-Click on CMD.exe and select Run as Administrator
    4) Type: net stop sppsvc (It may ask you if you are sure, select yes)
    Note: the Software Protection service may not be running, this is ok.
    5) Type: cd %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareProtectionPlatform
    6) Type: rename tokens.dat tokens.bar
    7) Type: cd %windir%\system32
    8) Type: net start sppsvc
    9) Type: slui.exe 3
    10) After a couple of seconds you will be asked for your Key - use the one on the COA sticker.

    And :

    slmgr /upk
    slmgr /ipk <Product Key>

    But it still no longer works.

  • To properly analyse and solve problems with Activation and Validation, we need to see a full copy of the report produced by the MGADiag tool

    (download and save to desktop - http://go.microsoft.com/fwlink/?linkid=52012 )

     Once saved, run the tool.

    Click on the Continue button, which will produce the report.

     To copy the report to your response, click on the Copy button in the tool (ignore any error messages at this point), and then paste (using either r-click/Paste, or Ctrl+V ) into your response.x

      - in your own thread, please

    Please also state the Version and Edition of Windows quoted on your COA sticker (if you have one) on the case of your machine (or inside the battery compartment), but do NOT quote the Key on the sticker!
