I assumed all environment variables would be exported to the process.
The problem is allowing environment variables to override registry
settings.

One idea would be to do both --- if an environment variable isn't set,
get the value from the registry and set the envronment variable.  If the
environment variable is set, use that instead of the registry --- that
might be the best of both worlds.

Yes, I think the above idea would work for that.
