I just tried it out on an XP machine and it did not work.  Perhaps you
had it in quotes?  Backslashes seem to work when they are in quotes.
As a side note, I have been running the 64 bit version of R on Windows
7 for several months now and have been very happy.  I have not had any
issues with stability or anything else to make me believe it is subpar
to the 32 bit version.
