Trigger-Started Services
Trigger-Started Services are new with Windows Server 2008 R2 and Windows 7. Before, services were typically started at system boot time and ran until system shutdown. Now, services can specify start and stop conditions (triggers). Common usage scenarios include: Device class arrival and removal Example: “Bthserv” starting on bluetooth device class arrival IP address arrival and removel Example: “Lmhosts” start on first and stop on last IP address availability Firewall port event Example: “Browser” open of NS and DGM ports Domain join and unjoin Example: “W32Time” start on join, stop on unjoin Custom ETW event Example: “AppID” start when SRP enabled Trigger meta-data is stored in the service registry key. You can use the “sc qtriggerinfo” command to view service triggers
