Of course, overwriting an existing HOME variable is a bad idea,  but Brian 
has a point. Naive Windows users are not likely to have a HOME  variable and in 
a corporate environment may not have write access to  C:\.  It seems to me the 
place to fix this is in Emacs, not in a  third-party tool. Something like the 
patch below.
This looks first for the HOME variable, then USERPROFILE (likely to be  
C:\Documents and Settings\%USERNAME% ), and then, as a last resort, C:/.
One could get fancier by playing with the default value of "emacs_dir" or  
using %HOMEDRIVE% instead of C:
