As has been pointed out before, it is pretty much a non-issue. The Windows installer ships with md5 sums for some local configuration files and if they are locally configured or touched by the installer, the checksums will not match. checkMD5sums is for package checking, it is not documented to be used for checking R.home(). 

Perhaps the Windows maintainer could strip those files from the checksums, but I wouldn't put it on high priority.
