One possibility is to only keep one version when the third digit in the version number changes and only create new fresh versions when the first or second digit in the version number changes. Thus when going from 2.7.1 to 2.7.2 you could just overwrite the 2.7.1 installation with the new 2.7.2 installation but when going from 2.7.2 to 2.8.0 you would create a new parallel installation of R. AFAIK that has always worked in the past and is what I normally do.
To overwrite your 2.7.1 with 2.7.2, when installing 2.7.2 just enter the old folder path in the "Select Destination Location" screen of the installer. All your old settings and libraries will be preserved. (You will no longer have a 2.7.1 version.) If you do want to create a new parallel installation when 2.8.0 comes out, say, there are links in http://batchfiles.googlecode.com discussing different methods. One of these is provided by movedir.bat or copydir.bat in the batchfiles collection which can be used to move or copy libraries safely as they will never overwrite.
