ConfigMgr 2012 R2 Windows Services

Posted on Updated on

A customer recently asked me what Windows services are used by a ConfigMgr 2012 R2 primary site.  It was a great question, to which I intuitively knew the main services, purposes, and impacts if they were faltering … but I had never seen or compiled such a list before.  In scouring through TechNet, I was unable locate a single source from product documentation.  As such, I created my own (outlined below) which generated from a variant of sources.

Note that SMS Executive is well known to have dozens of “threads” or operations that it performs.  I too could not locate a single source for product documentation with details on those threads.  So if you need that information, I recommend getting a copy of System Center 2012 R2 Configuration Manager Unleashed.
