Changing keyboard-type.

I have a question related to changing of your keyboard layout type. I'm going to let it get changed from azerty to qwerty. What I was wondering is; will this do any harm on the setup of my PC itself, since it's standard manyfactored in azerty. Why am I going to do this? Well, most games out there require qwerty, since that is the global layout or whatever and you can't change the hotkeys in lots of them out there. Most games I can't play descent enough because of the layout I currently have.

P.S.: Probably a pretty noobish question, but I'm just curious if it will do any harm. xD

As far as I know I don't think keyboards have Driver They are whatever the name is...Well in other words they work without drivers...At least for me have changed few...
