VS 2008 - WMI Registry Value Change Event?

I am working on a app that will monitor the registry for changes to [ProviderOrder] in [SYSTEMCurrentControlSetControlNetworkProviderOrder].

I have it 90% done with this
Imports System.Management
Imports Microsoft.Win32
Module Module1
Dim Watcher As ManagementEventWatcher
Dim Hive As RegistryKey = Registry.LocalMachine
[Code] .....

If I change [ProviderOrder.test] the app tells me the value was changed and corrects it. But it does the correction twice (because of UpdateProviderOrder changing the value). I thought that using RemoveHandler and AddHandler would take of that.
