I think Stefan has answered this so I will just add this about batchfiles. In the batchfiles distrirbution:

http://batchfiles.googlecode.com

is a file Rgui.bat. If you put that anywhere in your path and make your shortcut to that instead of to R itself then it will find the most recent version of R from the registry and start that so you don't have to update shortcuts each time you change R versions. There are also Rcmd.bat, sweave.bat and similar versions for the corresponding tasks. Using those you never have to set your path to R when installing or upgrading R on Windows.

The most recent version of batchfiles is for Vista and the next to most recent is for XP as per home page.

If you do want to move or copy your packages from one library to another movedir.bat and copydir.bat will do that. You can then use checkbuilt if its a major version change. There are also some other methods described in the Links on the home page.
