Hey guys just wanted to let you know this works in Win10x64 LTSB so you don't have to use the bloated Pro version.
What is the version of your LTSB? I am using Win 10 x64 Enterprise 2016 LTSB Version 1607 OS Build 14393.2125. Is this version with AMD Adrenaline Edition driver enough for more than 8 GPUs?
Don't know about AMD, and I don't remember which LTSB version it was off hand. But I still have the ISO though, so I'll check when I get home in a few days.
