It should retain it's new programming.

If you're talking about physically removing it from the PC then I'm not sure about that but I would imagine it should. You'd have to ask Andy to be sure.
Even with that in mind I would still program it and save your set-up to file so all you have to do is load it again instead of re-configuring everything over & over. If you want, rename the default file to something like default_backup & save yours as the default. Then have it load that on boot just in case.(Though you shouldn't have to do that. Just an idea, there's many ways you can do it.)
Hope that helps...
