Before the Update for 8.1, the Windows Store was accessible to users on a domain with special profiles. Both users with roaming profiles using computer set to delete the cached profile and users with mandatory profiles, could access the store. Why would you want to do this, some will ask. It is perfect for the training computers were the instructor is demonstrating an app. It worked great. After the 8.1 update (or an update near the same time) the Windows Store no longer allows access. "you can't access the Windows Store because you're signed in to this PC using a temporary or guest account."
The setting "Allow deployment operations in special profiles" is enabled in the GPO. The roaming users, for instance, have a MS account associated and can access everything else that needs a MS account i.e. OneDrive.
Has anyone else encountered this issue? Better yet, has anyone found a way to make this work?
