I have a powershell query which will list you all services running Manual Mode.

Get-WMIObject -Query "Select * from Win32_Service" | Select-Object name,Startmode -- list all services

Get-WMIObject -Query "Select * from Win32_Service Where StartMode='Manual'" | Select-Object name -- list services with manual mode start

I am trying to run it from xp_cmdshell . I will get back once I get it.
