I have a Logitech K800 wireless keyboard and Performance MX mouse running off of the same Unifying Receiver on Windows 10. All of a sudden, the keyboard doesn't type anything. The function keys work (I can mute, change volume, etc), but I can't input any numbers or letters.
The mouse still works just fine. The keyboard pairs correctly using the Unifying software and when I press a key on it, the icon lights up that the computer received input, but nothing happens.
I tried using the keyboard on another computer and it works just fine, so it must be a Windows issue. Strangely enough, my spare Mac corded keyboard works just fine (and that's what I'm using to type this)…
Searching for this issue and trying the few suggestions doesn't yield any success. Many recommend updating the device driver from the Device Manager, but the only keyboard listed is the corded Mac keyboard. Plugging the Unifying Receiver into different USB ports also doesn't change anything, nor does simply rebooting the machine.
What could possibly be causing this?

I found a solution that worked for me. Go to control panel - ease of access - make keyboard easer to use, then turn off "turn on filter keys"
