Hi, Im running Windows 7 student x64. When I go to Windows Update it takes a long time to load,once it does it shows a red shield with an x and says 'check for updates for your computer' and below this it says 'Find out more about free software from (null). click here for more details.' when I click it nothing happens. When I click the check for updats box a window comes up that says 'Windows Update cannot currently check for updates, because this service is not running. You may need to restart your computer.' I tried restarting and the same thing happens. Also, when I use the antivirus update within Comodo Internet Security 4 it says failed to retrieve update. check your internet connection and try again.
