I know that Windows 8.1 is supported only with ConfigMgr 2012 SP1 CU3. I tried to deploy Windows 8.1 without CU3 in our production environment because we havent installed CU3 yet. It works expect the Domainjoin. Tasksequence shows that domainjoin was successfully but after OSD the System wasnt in the Domain.
So i will Update our environment to CU3. Do i have to Update the Client Version too on all my Clientsystem or is it possible that Non-CU3 Clients work with CU3 Primary Site.
We only use ConfigMgr 2012 for OSD. No Software Deployment with Configmgr 2012.
