Win32 service by typedef (flatassembler.net)

Get DbgView (http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx)

Run "InstallSvc.bat" to install and start service.
Run "QuerySvc.bat" to query the service info.
Run "UnInstallSvc.bat" to stop and uninstall service.

DbgView will show service strings.

NOTE: Make sure you choose "Capture Global Win32" in DebugView since the service is in session 0.

Enjoy.
