yep. when i was working OS/MVT I used to hate people who wanted to
install an SVC. 

and so it is with Win7: if your app needs to modify the O/S then your
app has to be vetted just as though it was the O/S.  because when it
"hooks in" -- it has to be treated that way.

obviously you would not want to allow any and every app program to do
that... if you did you'd have a mess on your hands. Don't we?

I have always felt the registry should be for the O/S use only.  App
Programs should use their own .ini files.

one of the things we have failed to recognize is that the computers for
hobbyists, experimenters et al are different from the computers for
commercial/network/business applications.
