Turn off auto-restart after windows update

It's sometimes annoying when I come to the office next morning and find my development environment (it's a virtual machine) restarted automatically without my permission.I install Windows 7 Ultimate as my operating system and by default it will restart the system automatically after the windows update has been done (although you may argue that I should've changed the default settings when I installed the OS at the beginning). But as a developer, you won't like being interrupted by this when you are in the flow. Here's how we can disable the auto-restart feature.

1. Go to Run.., input gpedit.msc and click OK.
   
2. Expand Computer Configuration-> Administrative Templates-> Windows Components-> Windows Update and you will see a setting called No auto-restart with logged on users for scheduled automatic updates installations in the right pane.
   
3. Right-click on this setting and edit it.
4. Select Enabled and click OK to take effect.
   
5. (Optional) Repeat the above steps on the server hosting your virtual machine.
