Hi All
We have upgraded to SCCM 2012 1702 with hotfix KB4019926 installed, everything seems to have installed fine.
I am using the pre-production client which appears to be working a treat and turned my attention to OSD task sequences to test the new client on a build.
The task sequence is ignoring the pre-production client despite the option "use pre-production client package when available" being ticked and instead installs the current production client.
If i change the task sequence option to use the pre-production client instead of the production client it installs fine
