Hi,
You need to open the Group Policy Editor and edit the Windows Template for Auto Updates. ?There are a number of different options which control the updates. ? The only thing you need to be careful of is leaving the computer unprotected but you'll have control when you deploy them
In?Group Policy?Object?Editor, expand Computer Configuration, expand Administrative Templates, expand?Windows?Components, and then click?Windows Update. In the details pane, click?Automatic Update?detection frequency, and set the option.
