I thought the changes in 1607 to the "Education" version (turning off the store by default, etc.) sounded hopeful, so downloaded an .iso and applied it to a couple of computers. Sure enough, our old friend Candy Crush is gone...but on signing in, domain users get "We can't sign in to your account. The problem can often be fixed by signing out of your account and signing back in. If you don't sign out now, any files you create or changes you make will be lost." Needless to say, signing out and back in just gives the same opaque message. Users cannot access their Documents, etc. This is on a domain joined computer with roaming profiles and folder redirection.
What might cause this? I tried asking on TechNet and got crickets...
I'm really regretting having gone down the Windows 10 path. Too many hours trying (and mostly failing) to make the so-called "Education" edition suitable for an education environment. Everything I was reading about 1607 for Education sounded encouraging, after the 1511 debacle.
