Math Input Panel Windows 10

I tried to use the Math Input Panel in Windows 10. The formula will not copy to the word processor. But I believe the underlying problem is that the formula doesn’t get picked up by the clipboard…so there’s nothing to paste.
I checked the Microsoft support – nothing. The uninstall instructions don’t work. In the “Turn Windows Features on or off” there’s no listing for Math Input Panel.
I renamed mip.exe and moved it to another folder and figured on a reboot Windows would copy it from a back up. It didn’t.
Anyone have experience with refreshing Windows Accessories?
