    As a first step, stop the ‘Automatic Updates’ service on your PC. Navigate into Start -> Run from the home screen and type services.msc into the available field before pressing the ‘OK’ button. You can then double click on ‘Automatic Updates’ and select the ‘Stop’ option. The next step required is to delete all the content from the ‘Download’ folder. This time, you need to type %windir%\SoftwareDistribution into the field that appears after selecting Start->Run and press the ‘OK’ button. Quit the current window and type http://windowsupdate.microsoft.com into the address bar after launching Internet Explorer. Run a custom scan afterwards and clear off the checkbox next to KB951847 for hiding it. Install the ‘Root Certificate updates’ visible under ‘Optional Software’ updates, but hide all other ‘Optional Software’ and ‘Optional Hardware’ updates. Finally, start the ‘Automatic Updates’ again by selecting ‘Start’ option after double clicking on ‘Automatic Updates’.
