1. 180206 is rather old build
2. Num Lock works OK in my tests in the current build in Win 8.1

At first time I tested it on ThinkPad X220. However, I've just checked the same build on ThinkPad 25 (which doesn't have physical NumLock key) with on-screen keyboard and it seems to work fine. I'll check if Windows recognizes switching NumLock state on X220.
