We have decided not to go this way, but just for completeness:

Environment inheritance works the same way on Windows as on Unix. When
a process is started with a modified environment (one of the plentiful
arguments of CreateProcess() et al.), only that process and its 
descendants see the modification. I had not planned to set a system-level
or user-level variable.
