A simple Windows PS/2 filter driver based on the sample from Microsoft that remaps some keys on the Dell XPS 15 7590's keyboard to my personal preference.
To run in a secure manner, try this.
To install, do this (use elevated "x64 Native Tools Command Prompt for Visual Studio 2019"):
cd bin_folder
"C:\Program Files (x86)\Windows Kits\10\bin\x86\Inf2Cat.exe" /driver:. /os:10_19H1_X64
