The CTRL key on my keyboard has been annoying me for days now. Commands like CTRL+A, CTRL+C don't work sometimes and its results in just A and C being printed on the screen.

This happens with both CTRL keys (both left and right). I've removed and cleaned both keys on the keyboard, but this does not resolve the problem. The normal behavior for these modifier keys work only some of the time, so the problem is intermittent.

I have a dualboot of Windows and Linux, and the modifier keys work great on the Linux installation. I've reinstalled Windows in an attempt to fix this, but it's still not working.

    Since the Ctrl key works in Linux, you know there is no issue with the physical keyboard or related circuitry; the issue must be something in Windows stealing the key press. Look to 1. Windows Accessibility Features, such as Sticky Keys: helpdeskgeek.com/windows-10/… and 2. Third-party tools that hook into the keyboard, such as AutoHotkey and Clavier+.

  • Well, if it's not a problem in Linux, there's very very low chance it's a rather weird hardware issue. Are you sure you reset everything on Windows?

  • Hi @Destroy666, yes, i did a reset from settings, purging all files and apps. I did not do a clean install. I'm planning on trying a repair install because this problem started after a rough shutdown where my pc resumed from disk check utility.

It is possible that one of the Sticky Keys Settings are producing the symptom you are experiencing. In Settings, go to Keyboard and

  • Turn off Sticky settings
  • Turn off Toggle Settings
  • Turn off Filter settings
  • Turn on Make it easier to type (turning these on will show you if this feature is the cause).
