You can override the default location of the front end preferences path 
from

	WINDOWS DRIVE:\Program Files\Common Files

to whatever you wish using the undocumented environment variable
MATHEMATICA_PREFERENCES.  You can add this to your AUTOEXEC.BAT
with something like

SET MATHEMATICA_PREFERENCES=C:\Prefs

Hope that helps!
