"I would not consider services.msc a "normal user interactive method" since regular users don't use it."
And is there an API or command line way of doing that? Like there is with net stop service? Or quick edit to the registry?
What is meant by normal user interactive is a way for a non elevated or even elevated account to be able to turn off the application without have to manipulate windows or screens.. If a normal account can send say a net stop command, or even a elevated account net stop antivirusservice -- that would not be good Or manipulate a simple reg key with a simple command
It is more than the OP that does not understand this basic concept?
