There are two ways, one is going directly to the REGISTRY, there is an entry
for all the variables you see in the "environment variables" dialog, you
will probably need to be logged as administrator for that. Look MSDN for
more info.

The other way is to use the WMI API to access that in a more transparent
way, but with overall same results. WMI is well documented (although it is
an extensive API) in MSDN.
