Windows 10: Not being able to use spacebar when holding Shift or Ctrl Key.

I don't know the reason behind this but suddenly I can't use my spacebar key when I'm holding my Shift or Ctrl Key. My spacebar is working but for some reason this only happens when I'm holding shift or ctrl key. I have no clue of how this happened nor I have done any changes to my settings before it happened.This happens in almost every single program, My Windows Version is Version 20H2 OS Build 19042.928

:)

CTRL+SHIFT+8 and some others not working

Okay thanks. Didn't know that tool.
It does list Ctrl+Shift+, 3 & 8. But it doesn't say what they're registered to. (And nothing seems to happen when I press them.)

The tool turns up a very short list, by the way, compared to the screenshots on that site. Just these three plus:
Hot Key : Alt+Ctrl+Delete
Hot Key : Alt+Ctrl+J (I know what this is from)
Hot Key : Alt+Ctrl+K (Kindle)
Hot Key : Alt+F4

 

Shift/ctrl key problem.

Hi Jovan,

The issue you're experiencing is probably due to incorrect settings. A Windows Ease of Access feature called
Filter keys is an accessibility function that tells the keyboard to ignore repeated strokes. When this function is enabled, it ignores whatever key is pressed down or repeatedly pressed. To verify this, follow the steps below:

• Open Control Panel.
• Click on Ease of Access.
• Under Ease of Access Center, click on Change how your keyboard works.
• Under Make it easier to type, click on Set up Filter keys.
• The Turn on Filter Keys should not be checked, as well as
  Turn on Filter Keys when right SHIFT is pressed for 8 seconds.

We also suggest that you play around with the features and check which one works best for you. If the issue persists, let us know.
