Press Windows + R and type in regedit
Windows will ask for your admin permission, press yes and go to:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout
Right click to create a new binary value: Scancode Map
First line is filled with zeros, until the next line (16 zeros to be precise)
After that, 02 00 00 00 is the header, where 02 means "one remap"
As you have more and more remaps, you increase that number
I think it uses hex, so base 16 rather than base 10
You only need to change the first number, the 6 zeros after stay the same way
Now comes the actual remap
1C 00 3A 00 where 1C00 is enter and 3A00 is capslock => remapping capslock to enter
00 00 00 00 at the end of the map: there was a header, well this is the "bottomer"

Don't forget to reboot your computer for the changes to start working!
