Updating Hyper-V Core Server from 17763 to 19042
I have a Hyper-V Core Server that is sitting with an older OS Build. I cannot find any information on how to update the OS Build and the Windows Updates through sConfig doesn't seem to update the OS....
You'll need to clean install it. You cannot in-place upgrade LTSC to semi-annual channel build.
