Windows 10: E-Yooso Z-88 Gaming Keyboard Not Working

Hello, this is a very extreme issue. So, the day I posted this, my brother wanted to borrow my E-Yooso Z-88 gaming keyboard, all he did was change the key switches, but when I got it back and plugged it back in, the keyboard did not work. Can anyone help?

Keyboard Volume Keys not working while in-game

I happen to have used the Tt Challenger Pro keyboard in the past, and the volume keys worked flawlessly in every game, so it's indeed a weird problem. I would suggest the same thing sneekypeet suggested, using the keyboard software and assign this function to a hotkey, but you said that didn't work either, so yeah...

 

Control-Z Not Working System-Wide

Thank you @StefanoTamiotti and @Vijay_Verma
for your replies. The good news is that my problem has been resolved! The bad news is that I have no idea how or why, or who to credit with the answer.

I started by running an SFC scan, and got a clean bill of health ("Windows Resource Protection did not find any integrity violations"). Then I tried the online keyboard tester, which showed that my Z key and Control key were both working fine. Then I tried
to use CTRL-Z using the on-screen keyboard, which I figured would not work since it appeared that my hardware keys were working fine. But surprisingly, the OSK triggered undo just fine. So then, thoroughly confused, I tried CTRL-Z using my physical keyboard,
and it also worked fine!

So somehow, one of those steps solved the problem, but I have no idea which one. Thank you both for your quick replies and suggestions!
