'AutoHotKey permanently changed my keyboard keys, even at the bios level

Recently installed AutoHotKey to remap some keys in order to play a video game. It seemed simple/attractive enough at first. Was not really sure of how it worked but found the .chm file in the download which states in the first line of Usage & Syntax/Using the program:

AutoHotkey doesn't do anything on its own; it needs a script to tell it what to do.

Sounds 'secure' enough to me. Seems like mature software. Maybe overkill (now I know it certainly was overkill) but let's just see how it works.

My remapping was simple enough: change the AWSD keys for the LEFT-UP-DOWN-RIGHT keys. Script syntax is simple enough, just used an example that comes with the install files. Works essentially as expected. Got an annoying pop up after playing the game for a bit from AutoHotKey saying "you've pressed mapped keys 600 times" or something like that. Which was only a little annoying, so I ignored it the first few times. The game I play is real time so getting a even a 5 second interruption while in a match would mean certain loss, so I decided to just disable the script and uninstall.

Lo and behold: when I stop the script, the keys continue to be remapped. Was there some background process running? Maybe. I rebooted only to find that on my Windows login screen my keys continue to be remapped. Huh? Did AHK mess with some registry bindings or something? I do not know that much about how Windows works, but my vague recollection is that registry bindings is something is active once the OS is active. I search on the web for say 1 hour before I give up for the time being and I end up activating the script again in order to write normally. This works as expected and I literally forget about it until any time I have to reboot.

Honestly a minor annoyance, but due to the world changing very quickly I lately have very few precious minutes that I can actually sit down on my desktop, whereas I used to be able to spend hours on this type of computer issue in order to get to the bottom of it. In other words, my current solution felt good enough. But not anymore. I think something more serious and possibly nefarious may have occurred. I don't want to seem dramatic but I just discovered something else a few minutes ago.

I have a Linux installation on another drive and I just happened to want to load it up after my last Windows blue screen (have gotten a couple of those lately, literally 2 in the space of 2 days and this had maybe only ever happened once before, like 2 years ago, so I am a already concerned about a possible deeper issue). My firmware/bios has a password and guess what I found when I tried inputting it: the keys were still remapped.

At this point I am at a complete loss. I didn't even think this sort of thing was possible. Some OS level software caused a change that was able to be reflected on the bios? Did it affect the keyboard driver? A driver that both windows and the motherboard bios use?

What else have I tried or looked at:

Device Manager claims my Keyboard has 3 instances of "HID Keyboard device". Not entirely sure why it shows 3. Properties show it has 2 driver files: kbdclass.sys and kbdhid.sys, which I suppose are some standard drivers. Not sure how to proceed.

My keyboard is inland (cheapest i could find at microcenter) i am not sure why I cannot find the website for that company. Found some drivers on reddit but they are on some sysadmin's google drive. I will download that exe when i am desperate...

UPDATE

I 'solved' the issue bye getting another keyboard (an old IBM KB-0225) and everything is now in order. I tried disconnecting the Inland keyboard and reconnecting, but after reconnecting I was still experiencing the same issue.

I don't know if I should close this question as there is no longer an issue, but I would like to see if anyone has any other additional theory as to why some software/driver changed occurred inside a keyboard device. As far as I knew, these devices have not internal memory other than possibly some logic gates.



Solution 1:[1]

There must be a background process running.

to check that:

note : For windows 10

  1. On your taskbar, click on the ^ button (skip this step if there is no such button)
  2. right-click on the autohotkey "H" logo sign.
  3. click on "exit"

If the above steps do not work, try keeping a watch all the time, to see if you notice something uncommon.
