Just asking because 9.4 pdf docu says nothing about it ?
Supported Windows Versions
UEM 9.4 is fully supported on Windows 2016 LTSB. I guess we should really clarify our docs, given your question and the recent UEM 9.4 supportability with Windows 10? thread :-)
(And hopefully that clarification will also help me, as I initially responded to your question as if it were about Windows 10 LTSB...)
