Windows 10: Ctrl+Shift Keystrokes Not Working

I am having issues with the Ctrl+Shift keystrokes on my Windows 10 system. I've tried changing my typing settings, I've tried updating my sysytem, I've tried looking for drivers, I've tried looking at my hotkey settings, and nothing seems to work. This just suddenly happened withing the past few weeks, and It's become increasingly annoying. How do I fix this?

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

 

CTRL+SHIFT keyboard combos not working

I've been using Windows 10 at home for a couple years. I use numerous keyboard combinations that involve CTRL+SHIFT. For example:

• CTRL+SHIFT+V to paste text without formatting
  
• CTRL+SHIFT+T to reopen a closed tab in Google Chrome
  
• CTRL+SHIFT+E to export photos in Adobe Lightroom
  

And so on.

My problem is that all CTRL+SHIFT keyboard combos stopped working. I don't know how or why! Suddenly one day they didn't work any more. Whenever I press CTRL and SHIFT at the same time, I get a beep, and the desired combinations don't do anything at all. This problem persisted for more than six months. I tried everything I could think of, researched many forums and message boards. Nothing worked! I gave up and learned to live without it, though I was quite frustrated.

Two weeks ago I noticed the functionality had returned. CTRL+SHIFT keyboard combos worked again! No more beeps! What changed? I don't know. I enjoyed using these shortcuts again, until about an hour ago when they stopped working again and the beeps returned.

And here's the kicker: midway through drafting this post, the problem once again went away. CTRL+SHIFT is working again. Hooray. But for how long?

I strongly suspect that I'm inadvertently turning some setting on and off. Can somebody please tell me what or how? This is kind of driving me crazy, and I don't want to be at the mercy of my own stupidity any longer. I can't be the only person having this problem, can I?
