Does anyone know how to change the Windows 8 lock screen, on the Enterprise version. All the instructions I seem to find only work on Pro or other versions of the OS.
With the November 2012 Update, MS added a GPO to manage the Lock Screen:
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”
Apply this GPO to get your custom image.
