    Left CTRL key not working properly


    Ever since I left the insiders build of windows (because I got sick of bugs and constant updates) and completely reinstalled windows to the latest stable version, the left control key won't work 100% of the time. The right one works just fine, and I've seen multiple threads on Google about it, but their solutions haven't helped.

    I've tried the Ctrl+Alt+Fn solution that people said worked, it doesn't for me.
    As for drivers, they're all updated/installed and it still doesn't work. Unless I missed something, but I made sure to agonize over which drivers to install and install the right ones for hours. It could be possible I need a driver or something because reinstalling windows removed all drivers.
    I tried going into the device manager and uninstalling all the drivers in the keyboard section and restarting my PC, still doesn't work.

    I don't think it's a hardware issue, meaning physically the Ctrl key is broken. It can't be because it was working 100% of the time before I went back to the stable version of windows.

    What I mean by "not working 100% of the time" is this:

    Before I used Ctrl+Alt+Fn:
    000000v0v00000vv0vvvv0000v00v000vvv0vvv0v0v0vvvvv000vv0v0v000vvvv0v00vv000v000vvvvvvv0vv0vvvvv00v0vv vvvvvvvvvvvvvvvvvvv

    After I used it:
    00000000000000000000000000000000v00000000000000000000000000000000000000v0000000vvv000v000v0v000v00v0 0vvvvv0v0vvvvvvvvvvvvv0v

    Sorry for the spam, but the 0's is when the Ctrl in Ctrl+V worked and the Vs is when the Ctrl didn't work at all, it only recognized me pressing V. If it wasn't obvious, I had "0" copied to show the success rate of the left ctrl key. Every time I attempted to paste a "0" I would hold the ctrl key down and press V, then let go of both keys and try again, and so on.

    So anyway, you can see even after one solution it sort of worked, then decided to stop. It should work ALL the time.

    If you're wondering, my version of windows is: 20H2 (OS Build 19042.867)

    Thanks in advance.

    :)

    Method 1: To check if Ctrl keys work in Onscreen keyboard.

      Large icons.

  3. Left CTRL key only works together with the left SHIFT key

    Hello,

    Starting from today while I was using FL Studio to copy some musical notes I noticed Ctrl+C and Ctrl+V weren't working

    I've opened the on-screen keyboard in order to check if the left CTRL key was working and pressing it alone doesn't show any input.

    But. when I tried to first press the left SHIFT key holding it and then pressing the left CTRL key together. both keys showed input. (right CTRL key works fine)

    Is there anything I can do to fix this issue?

    I've already tried to uninstall the keyboard's driver and then restarting the PC but it didn't work.

    Best regards,

    Me

    Left CTRL key not working properly

    Left ctrl -c v f a h x, none is working for the left ctrl key, but totally working for the right ctrl key

    Left ctrl -c v f a h x, none is working for the left ctrl key, but totally working for the right ctrl key. It's not a hardware

    problem, because ctrl + mouse scroll works for zooming out/in webpages. Used a second new keyboard, same thing.

    Tried the uninstalling keyboard drivers, didn't work. Please help! Thanks!
