KeyTweak

It's preferable to AutoHotKey as it doesn't run in background draining resources, relying on the more permanent registry tweak instead. Some games ignore changes made by KeyTweak, use AHK for them.

I have tried a handful of it's more popular alternatives and sadly non worked for me at least. In my case I wanted to remap the "" to the Insert button, due to the original key on my keyboard stopped working.

Must have if you have a Mac keyboard on Windows!

I remapped the volume up / down keys to control volume and changed the location of the Windows button. Super easy!
