默认情况下，“Get-Service”可以为您提供更多功能。许多Cmdlet都有格式定义，默认情况下仅显示特定属性。
您可以使用“Format-List*-Force”在顶层(=直接成员)上看到更多内容

PS> Get-Service -Name 'BITS' | fl * -Force

UserName            : LocalSystem
Description         : Transfers files in the background using idle network bandwidth. If the service is disabled, then any applications that depend on BITS, such as Windows Update or MSN
                      Explorer, will be unable to automatically download programs and other information.

但是有很多间接的(嵌套的)成员。您可以通过使用“Get-Members”或使用它们(例如$service.RequiredServices)来发现它们。

PS> $service | Get-Member -MemberType Property

   TypeName: System.Service.ServiceController#StartupType

另一种选择是使用WMIC，它提供了更多信息：
