That's along the lines of what I'm looking for, and I'm sure it'll probably do the trick, but what I was looking for is an actual windows keyboard layout, which uses the windows language bar etc. It's a reg file or something, which actually adds an extra layout to windows' own keyboard driver.
There are lots of different programs I can run that will accomplish the same thing, but it means I need to keep that program running at all times, taking up resources, etc. Those programs work by intercepting all keypresses and remapping them as need be.. This is a terrible way of doing it really.. It adds lag, reduces responsiveness, and if anything goes wrong it can interfere with programs and games, possibly even losing the ability to type till you reboot.
I'm not looking for a resident program you run on startup, I'm looking for an actual windows keyboard layout that lives in windows' own control panel.
