Start Windows Services from PowerShell according to StartMode.

In a previous post, I described how to stop and start MS Dynamics CRM services, this post is just a different way of doing it. The reason for looking for a different way is that the Get-Services cmdlet ignores the StartMode, i.e. if the service is disabled Start-Service will try to start it and fail so the solution is using WMI objects:

Get-WmiObject -Class "win32_service" | ?{$_.Name -like "mscrm*" -and $_.StartMode -eq "Auto"} | % {Restart-Service -Name $_.Name}‏

You might be wondering why this is needed, surely you should just uninstall the disabled service(s) and I would tend to agree, but sometimes it might be necessary to temporarily disable a service for testing purposes for instance, and by checking for the startmode you will only attempt to start services that can actually be restarted.
