I was thinking the same thing. Would that everyone was so diligent, eh?

The only reason the %USERPROFILE% portion is there in $HOME is because 
in the Windows environment variable settings, the value of HOME 
includes %USERPROFILE% but USERPROFILE is not itself set, so Windows 
doesn't expand the nested variable reference, it just leaves there in 
its literal form.

So you can set the HOME definitely / absolutely or supply a value for 
USERPROFILE so the expansion of HOME passed to newly created processes 
will include it. Somehow, though, I doubt you'd want your HOME 
directory to be in "/usr/bin/..."
