Problem
I have used one license key and want to switch my configuration to use another key. I tried to launched the uninstall wizard from "Add/Remove Programs" in the Windows Control Panel. When I reinstalled, the license still work. How can I modify my Visual Studio 2010 installation to use another key, and possibly without uninstalling and reinstalling? Sorry for not clarifying it at the beginning. Actually, a valid key is not available to me for now. Is there a way to remove the original license completely and use VS as a trial version for days.
