Windows 10 Taskbar Search No Longer Works

[SlackerKing]

I'm not sure when it happened exactly, but in the last few days, my Windows 10 taskbar search field has stopped working.
No matter what I type into it, a blank/black popup is the only thing that displays.
I did install 2 Windows Updates on 2/4, but I am not sure if they caused it or the weird issue where Parallels become "stuck" and the Windows 10 computer would never restart, so I had to force shutdown my MacBook.
Here are the two updates I installed:

https://support.microsoft.com/en-us/help/4532695/windows-10-update-kb4532695

Any thoughts on how I can fix this? While this Windows VM is only about 3 months old, it hasn't been used much until recently.

Looks like it may have been a global issue earlier and still impacting some people.
