How to disable or delay Windows 7 Automatic Update Restart Prompt

After every Windows Update, a notification is sent to the logged in user asking him to restart his computer. This is important from security point of view so the computer and your data is not affected by any malware or security holes. However most of the time a user is not in state of restarting the machine because you might have  video conversion going on or you might be doing a file transfer.
Since Windows 7, a very useful option that came was that you can postpone the notification to a max of 4 hours. This means that windows will not prompt you to restart your machine for that duration of time but if you want to disable this notification completely, you can use Local Group Policy Editor to disable restart notification completely or delay it for a longer period.

Instructions to disable the Automatic Update Restart Prompt :

• Type CMD in your command prompt
• Right click and run as administrator.
• Type sc stop wuauserv
  
• This will make the window disappear for that session
• So when you get next update you will have to use the same trick again.

Instructions to delay the Automatic Update Restart Prompt :
