Anyone wondering if this keyboard works under win 10, in my case it works perfectly (didn't try fwupdate one yet, but not sure if I will).
I just installed the win8 one and run it like any other driver setup with the keyboard plugged it. Every option in the app works even the T keys - tried launching app, assinging single key and macro - all work. I don't know if it matters but my version is the kb-mgu006us but when installing it said illuminated (while mine is regular g-unit).
