Service Function: Get-Service vs Get-WmiObject\Get-CimInstance #39

Closed ChrisWight closed 7 years ago

ChrisWight commented 7 years ago

Hi there,

The Service function allows you to specify a property which defaults to Status but due to using Get-Service does not allow you to check the StartMode, to get around this I changed the Service function to use

-TestExpression {Get-wmiobject -class win32_service -Filter "Name = '$Target'"}

and changed the default property to state which then lets you test either.

Is there a reason for using Get-Service over WMI or CIM?

Thanks, Chris

I think, intuitively, a Service test function would be backed by Get-Service. For scenarios where you need to use CIM there is a generic CimObject function.

In PowerShell 5+, Get-Service returns the StartType property. https://windowsserver.uservoice.com/forums/301869-powershell/suggestions/11699283-get-service-does-not-return-the-service-startup-ty

So, I see where you're coming from, but for this case, I don't think we should change how the Service function works.
