Windows 10: Space bar turning down volume

Hi, i don't know what could have happened, but from yesterday (2018 9.4) my space bar started lowering the volume whenever i press space, and whenever i press shift it acts like backspace. I haven't got a new keyboard or anything. And it became quite annyoying. I may have pressed something that acts like a shortcut but i don't know. Thanks.

Space..Bar

Hi Regina,

There are different reasons why your space bar and other keys are not responding.
For us to properly isolate your concern, we'd like to know the following:

• When was the last time that your space bar and other keys were working?
• Have you made any changes on your machine prior to this issue?
• Have you installed all pending updates on your machine?
• What is the build and version of your Windows?

In the meantime, we suggest that you run a
quick test scan

Diagnostic Tool. The tool will help us determine if the issue has something to do with the hardware or software of
your computer. If an error is detected, it will automatically fix and recommend other troubleshooting steps to resolve your issue.
