To me, it seemed more straightforward to do this outside R.  

Just set the environment variable R_LIBS in Windows to something like

R_LIBS=c:/R/Library

Then, delete your R installation. Install the new version and all
desired packages.  The add-on packages will be located according to
your environment setting, and future updates will not require add-on
packages to be copied or reloaded.
