One cannot change the Windows shortcuts, but one can intercept keys and change them on the fly.
AutoHotkey is a great program for remapping keyboard keys. Here are the steps to set this up:
- Download and install AutoHotkey
- Create a text file named startup.ahk and paste the following inside to map Ctrl+Alt+Right / Left to Ctrl+Win+Right / Left:
!^Right::^#Right
!^Left::^#Left
- Save and run the script to test its functionality.
- If it performs as expected, copy the script into the Startup folder
To find the startup folder in Windows 10, open "Run" (press Win + R, or search for it in the Start menu) and type either (without quotes): "shell:startup" for the current user, or "shell:common startup" for all users. Copy startup.ahk to the folder that opens.
