I am facing all these issues contemporarily:
1. Caps lock does not work properly: When I type it's something like "HELLo hOw are yOu"
2. Number keys, Shift keys etc. Do not work, instead the symbol appears when type Number keys
3. Every new tab opens in a new window.
4. The "Scroll Up/Down" feature does not work properly (sorry idk what it's called)
I tried Clean boot and the issue still appears and options like Updating or Deleting keyboard driver. Num lock key, but none of them helps.
I was facing these issues together a few weeks ago, they re-appeared all of a sudden.
I am certain that all the problems that I am facing are linked to each other, they seem to appear and dissapear together.
