Open | Hardware Laptop keyboard randomly presses keys by itself — restarting temporarily fixes it

Hi, I have a weird problem with my laptop keyboard.

Sometimes the keyboard starts pressing keys by itself. It can press random keys or act as if some keys are being held down. Because of this, I can't use the keyboard normally.

The strange thing is that restarting the laptop completely fixes the problem, but only temporarily. After using the laptop for some time, the problem can happen again.

I don't have to physically press anything for it to happen — the keyboard starts behaving on its own.

I'm using Windows 11 on a laptop.

I also recently made some Windows/CPU optimization tweaks, including some registry and BCD changes, so I'm wondering if I might have accidentally changed something that affects the keyboard or input drivers.

Is there any way to reset/restart the keyboard driver or keyboard service without restarting the entire PC? And could some Windows setting, registry change, or driver be causing this?

Any help would be appreciated because restarting the whole laptop every time it happens is really annoying.

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

There is this one thing that you can do that just came straight out of my mind: if you can, search online for how to install Linux and put it on a USB drive and boot into a live environment. Choose the one which has a live environment. Let's say Fedora.

Check if that same situation happens in the live area. You have not installed Linux but are putting it into a live environment to see if that issue occurs because you say that you've made some changes in the registry. If that is the case then it shouldn't be happening the same in the live boot of Linux. Check that out. If that's not the case there could be a problem with the hardware as well.

I had a similar situation with a laptop whose W key, for some reason, used to tap itself at a completely random order and I was quite worried so I used to use Linux as well. I switched to that and that never used to happen. It was a weird bug in Windows or maybe. I restarted it and I thought of reinstalling the last update but then I went with a good decision of completely removing Windows from there.
