Microsoft Service Control Manager

Service Control Manager (SCM) is a special system process under Windows NT family of operating systems that starts, stops, and interacts with Windows service processes.  It is located in %SystemRoot%\System32\services.exe executable.  Service processes interact with SCM through a well-defined API, and the same API interface is used internally by the interactive Windows service management tools such as the MMC snap-in Services.msc and the command-line Service Control utility sc.exe.
