Essence of the post is :::
“To date, only one method has been identified that will disable all visible machine restart notifications. This method uses a combination of domain GPO Adm template settings and Local Policy Adm template settings with Windows 7 and Windows 2008 R2. The specific Local Policy configuration settings are new with Windows 7 and Windows 2008 R2.
