After expanding variables, I was able to look for where
ProfileImagePath is equal to $USERPROFILE. YMMV.

I was able to come up with a short script that does the
equivalent of "mkpasswd -d -u $USERNAME" on my system.

However, I did not know what to do about the group
number. Based on my system and other e-mail I've seen,
I just hardcoded 513 for now, but that's probably not
universally correct. Is there any way to get that info
from the registry?

P.S. Here's the script I used. It's in Python, and only
works using the WINDOWS version right now since Cygwin
Python doesn't support the _winreg module.
