Edit/update:

Some are suggesting that I caused this by accidentally pressing both the Windows key and the L key AND the period key all at the same time...

But when I got home and tested on my windows 10 machine 1809 (17763.195) which is recent all the way to end of last year Dec 2018, I can NOT replicate or duplicate this event, so if it was an update, which update in the last few days would have caused this bug?

It looks like you did it by accident.

 

Keyboard shortcuts to launch emoji panel on Windows 10:

• Windows Key + . (Windows key plus period, or)
• Windows Key + ; (Windows key plus semi-colon)
