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...

Keyboard letters don't work to login to Windows User account.

Hello,

For the last few days, I can't seem to be able to login to my user account on the windows login screen.

When it boots and asks me to type my user password, I try typing but the letters won't work. The numbers work fine, as do the system keys (ctrl, enter, space, shift etc..) but I can't type letters. My mouse works perfectly.

Sometimes after a few reboots, it does let me type again but then stops working on the next reboot.

I've tried using the Ease of Access on-screen keyboard provided in the windows login screen, but when I try hit the letter keys with my mouse, they don't work there either.

I finally figured out I can choose the option to login via my microsoft account instead of the user password, and when I select the microsoft account option, the letter keys work fine to type the password!

I'm running Windows 10 on my Dell XPS 15 (9550) with touch screen.

I don't know if it may be related but I did update my dell with the suggested updates (some bios one, alongside a few others) around the same time the issue started.

What could it be?

Thank you.
