I use both windowsservercore and iis on WIndows 2016. I see there is now an ltsc2016 version available for both of these, but I can’t find any information about it. How does it compare to 10.0.14393.1944?
Here is details https://docs.microsoft.com/en-us/windows-server/get-started/semi-annual-channel-overview
In nutshell it’s the same thing you are using now, just labeled differently. On the other hand SAC tags are newer edition with faster release cycle and shorter support cycle
