Powershell - create new WMI namespace

Hey ,

I have found the following script in VBS to create new WMI namespace (http://blogs.technet.com/b/heyscriptingguy/archive/2007/07/25/how-can-i-create-a-new-wmi-namespace-under-the-root-namespace.aspx)

strComputer = "."

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root")

Set objItem = objWMIService.Get("__Namespace")
Set objNamespace = objItem.SpawnInstance_

objNamespace.Name = "ScriptCenter"
objNamespace.Put_

How do I translate it to powershell ? :) Thanks
