Windows 10 1903 Group Policy Issues after OSD
Hi, We've recently started deploying Windows 10 1903 (First Win 10 version too...) with SCCM 1902 with MDT and group policy appears to apply, according to the logs but then we find certain settings not actually applied, even though a gpresult shows them as being applied. Checking the various reg keys etc. for our policy settings on a client, I have seen that all of our GPO settings get applied and then some but not all get mysteriously removed, for example the Interactive Logon message gets applied but then removed, as in the registry value is removed. Running a gpupdate /force after this has happened, appears to fix the issue. However using the SMSTSPostAction variable to run a script or command to update Group Policy, doesn't work either, the script/command runs (As per log files) but the above does still occur until we run a gpupdate /force (A ordinary gpupdate does nothing, so most of the time reboots etc. do nothing). We have no Group Policy related Group Policy settings (As in the ones that control whether CSEs process during slow links etc. and whether they process even though there are no changes) and we cannot find any other reason for this not to work correctly. I think until we find a fix, using the RunOnce reg key/value maybe the workaround... Would someone at Microsoft be able to confirm whether this is a confirmed issue at Microsoft and whether there is a fix for it please? Or if there is a fix incoming as potentially some of our security related GPOs are not being correctly applied. Many thanks, Luke
