Well, i always would like to test Windows 10 LTSC 2019 but unfortunately (never understand why) i can't install it cause the process hang up indefinitely with initial windows logo. I think a lot of reports about the issue was automatically sent to MS at the restart after several installations abort. And indeed now, to my surprise, i can install every version of 1903 (from Home to Enterprise) without any issues. So the situation on this device is: W10 installable - 15_07/11;1607;17_03/09;1803;1903 W10 uninstallable - everything related to 1809 The drawback is that LTSC 2019 belongs to 1809 branch, so until they release a new iso (2022) i was stitched to LTSB 2016. What can i do to make/lighten the enterprise 1903 and make similar to a LTSC 2019? Also, i really prefer to avoid reserved space of 7GB.
