Microsoft Wired Keyboard 600 not working

[knrd69]

So I've been using this keyboard for almost a year. Today I boot up my PC and all the keys except volume control keys stopped working. The drivers are showing Code 19 so I reinstalled them and the code was still present. I also tried booting into Safe Mode. It's not even working in Safe Mode. I can only use this keyboard in BIOS. Is this an issue with my OS? I'm using Windows 10 Home x64.

Have you tried a different USB port?
Have you got another computer you can test the keyboard on?

Yup, tried every single USB port, doesn't work. Also used a different keyboard, didn't work either. I think it has nothing to do with my keyboards, rather Windows itself.

I think you're right, unless you happen to have two dodgy keyboards.

You could always try reinstalling windows/repairing it to see if that fixes it
