Get all the services on the computer.:

PS C:\> get-service

Get all the services on the computer Server64:

PS C:\> get-service -computername Server64

Get services with names that begin "WMI" and sort the result by the service status (running/stopped):

PS C:\> get-service wmi* | sort-object status

Display only services that are currently running:

PS C:\> get-service | where-object {$_.Status -eq "Running"}

Status is only one property of service objects, to see all the properties: get-service | get-member
To retrieve the description of a service use the Win32_Service WMI class:

PS C:\> get-wmiobject win32_service | where-object {$_.Name -eq "Schedule"} | format-list Name, Description
