To make my Windows 10 system act more like the macOS behavior that I'm accustomed to, I remapped my keyboard following the instructions of Orwellophile when they answered the question of how to Switch Ctrl and Alt with AutoHotKey without messing up the Alt-Tab switcher? here on Super User.

It works OK – most of the time – but I'm finding it also screws up a bunch of other (Adobe) shortcuts that I use all the time. So I think I should go back to the default settings and remap my brain instead.

So my question is: how do I undo the registry edit? I didn't make a backup prior to the change, and even if I did I've been using the computer for a couple of weeks now.

Another approach suggests...

If you do not want to use third-party applications to reverse the SharpKeys modifications, you can cut out the middleman and edit the Registry directly.

Open the Registry Editor by navigating to C:\Windows\regedit.exe in Windows Explorer. Once it is open, navigate here:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout If there are entries named Scancode Map or Value Scancode Map, delete them. Those entries are what causes Windows to remap incoming key presses from the keyboard.

Once you are done deleting them, restart your computer. Key mappings will be reset to their default settings.

Download Keytweak (available at https://keytweak.en.softonic.com/ and many other popular download sites), run it and press the Restore All Defaults button.

Adding another registry with empty mapping will override it. I'm not sure but I've tried and it removed custom registry for my keyboard.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout] "Scancode Map"=-

Add above registry and restart your computer.
