Windows 10: My keyboard automatically pressing ctrl. My ctrl button turn into ctrl+shift command...

and my other letter "K" letter everytime i press it it turns into ctrl+k I'm so frustrated cause sometimes the comma "," button also clicked on it's own

:)

 

Ctrl Alt Del, Vista

The whole Ctrl+Shift+Esc should be used to get that crazy screen with those options and Ctrl+Alt+Del should bring up TM.

 

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?

 

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
