Windows update service not running

If you get the error message that the update service is not running, the first thing to check is that the service is on automatic. If it is, then go to your automatic updates settings, and turn them completely off. It's the "not recommended" setting, never check for updates. After you have set updates to this, go to the control panel and manually check for updates. It worked well for me; it checked for the updates, installed them, and afterwards I could set it to automatic updates and it worked. This was on a Windows 7 system.

Thanks all for the support! But I think its a corruption problem and as I am looking into windows 7 programs some of them are not working anymore. so i decided to put in the win 7 dvd and did another upgrade from win 7 itself and it worked now after 4 hours of reinstallation
