Well, of course, if you're using the API routine rather than going behind
its back, then when M$ change the registry format, the code will continue to
work....... that is the whole idea for an API.

See, I think that the best generic solution to this situation is to write
code that dynamically links to ChangeServiceConfig2 if available, and falls
back to writing hard-formatted registry keys/values only if that is not
available. That's both backwardly *and* forwardly compatible, as opposed to
the current solution, which is fragile.
Can't think of a witty .sigline today....
