In

http://cran.r-project.org/contrib/extra/batchfiles/

there are Windows XP batch files that you can use that will automatically locate R using the registry and run it so that you don't have to change your path. Just place them anywhere in your path. See the README for more info.

I use them for building packages and also have a shortcut on my desktop to one of them with a shortcut key defined so that after installing a new version of R it automatically uses the new version without any action on my part to reset the shortcut and shortcut key.
