The update “Windows 8 and Windows Server 2012 cumulative update: November 2012” adds functionality to the Control Panel group polices that allow an administrator to designate a lock screen image on their Windows 8 and Windows 2012 computers. This setting lets you specify the default lock screen image shown when no user is signed in, and also sets the specified images as the default for all users (it replaces the inbox default image) Some restriction apply. See the Restrictions section below.
The new group policy is named “Force a specific default lock screen image” and can be found in this path in the group policy editor: “Computer Configuration\Policies\Administrative Templates\Control Panel\Personalization”
Requirements:
To deploy the new “Force a specific default lock screen image” GP the following requirements must be met:
- The update “Windows 8 and Windows Server 2012 cumulative update: November 2012” must be applied to all Windows 8 and Windows Server 2012 computers that you want to deploy customer lock screen images to. This is required as the Control Panel group policy client side extension must be updated to enforce the group policy
- The group policy used to deploy the custom lock screen image must be edited on a machine that has been patched with “Windows 8 and Windows Server 2012 cumulative update: November 2012”
