We use SCCM for our OSD. During the task sequence we install the ZCM agent. Everything installs correctly, there are no errors, logs are clean, but once the machine comes up the Windows 10 (works fine on Win 7) logon screen is blank, there are no fields to enter credentials. If you boot to safe mode then login the problem is solved.

The issue exist on both 11.3 and 11.4.2 agent.

Weve tried waiting for the istall using a script (http://christianlehrer.com/?p=226), installing the agent after the task sequence has finished (using SMSTSPostAction), using a custom agent with no zone details, nothing works. If we remove the ACM agent install form the task sequence the problem is goen.

Any ideas much appreciated.
