Service Control Manager

Service Control Manager (SCM) is a special system process under the Windows NT family of operating systems, which starts, stops and interacts with Windows service processes. It is located in the %SystemRoot%\System32\services.exe executable. Service processes interact with SCM through a well-defined API, and the same API 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. Terminating this file is used as a method of causing the Blue Screen of Death.
