    Activation error 0x80070426

    Ok, I bought a new Toshiba laptop last year preloaded with Vista. A week ago,
    I noticed that the control panel was no longer opening up, and nor was the
    built-in Chess Titans game, or the Personalize options by right clicking on
    the desktop. To find out what was happening, I went to "System" by clicking
    on the "Control Panel" from the link on the left once you open "My Computer".
    It says there that Windows is not activated. I go...ahhh!! this must be the
    reduced functionality mode then! I dunno what caused it, all I installed in
    the past few weeks were some Windows Updates (btw, even Windows Update
    doesn't work now). So I clicked on the "Activate Now" button, and a window
    came up saying:

    Error 0x80v070426
    The service could not be started.

    So I went to "Services", and manually started all the services that were not
    started. When I started the SL UI Notification Service, I got the following
    error message:

    An unauthorized change was made to Windows.

    You will no longer receive notifications, including those about your license
    and activation. Use the link below to find out how to fix your system.
    Error: 0x80070426
    The service has not been started.

    And when I click on the link in the message, it takes me to the Windows
    Genuine Advantage website. There, I click to find out whether my copy of
    Windows is genuine, and it says that it is not.

    Now, I'm pretty sure that Toshiba does not pirate software, so the only
    valid explanation is that I must have installed some software on my laptop
    that is incompatible with Vista (...and boy, there are tons of those!). So I
    uninstalled pretty much everything I had installed on it the last month, and
    even used System Restore to restore it to a previous date. However, the
    System restore failed twice for some unknown reason.

    So, keeping aside the incredibly dumb and absurd policy of Microsoft to
    harass their customers by invalidating Windows the moment an incompatible
    software is installed, can somebody please suggest me a way to activate
    Vista? (I didn't know this, but it seems that I have to pay Microsoft to
    utilize their technical support to fix a problem that was created by their
    "genius" engineers and policymakers in the first place.)

  • St Share,

    In your Microsoft Genuine Advantage Diagnostic Tool (MGADT) report it shows the error code "Online Validation Code: 0x80070426". This means that the Software Licensing Service has stopped. Windows Vista uses this service to check itself and confirm it is Genuine. When the service is stopped, Windows Vista is unable to confirm its own Genuine status and may show Genuine or Non-Genuine. The fact that the Service has stopped is also, most likely, the cause of other issues you may be experiencing (such as not having access to the Control Panel).

     Please try the first set of steps and if it does not resolve the issue, move on to the next set.

     The first sets of steps are how to set the Software Licensing Service to start at each Windows Vista Start-up.

     1. Click Start button and in the Start Search box type in:  services.msc

    2. Press the Enter key on your keyboard

    3. The Services window should now open

    4. Scroll down to Software Licensing, then right-click on it and select Properties

    5. Under the General tab, click Stop button.

    6. Set the Startup Type to Automatic, and then click Apply

    7. Next, under Service Status, click Start button.

    8. Last, restart your computer.   

     The second set of steps is the Manual steps to Force Start the Software Licensing Service. Once you type the net start slsvc command and hit Enter, if you receive any error, then, for some reason, Windows Vista is not processing the command correctly and the issue is larger than just a Software Licensing problem. In which case, I would suggest contacting Windows Vista support below: http://support.microsoft.com

     If you have access to the Start button:

    1) Click Start button

    2) Type: cmd in the Start Search field

    3) At the top the Start window, you will see cmd.exe

    4) Right Click cmd.exe and select Run as Administrator

    5) Type: net start slsvc

     If you do not have access to the Start button:

    1) Click the option that launches an Internet Browser

    2) A Browser will open, type: %windir%\system32 into the address field

    3) Find the file cmd.exe

    4) Right Click on the cmd.exe and select Run as Administrator

    5) Type: net start slsvc

     Thank you for visiting the Genuine Advantage forum.
