Disabling automatic device detection programmatically

Hello everybody! =)
Please help me with the next problem:
How to disable automatic device detection programmatically (in C#, maybe using winAPI)? When I remove a device from a Device manager, I have to disable auto detection after rebooting windows. As I read, I should disable Plug&Play in registry. It seems I've done it (it works on Win XP, but not in Win7)
How I did that:
Disable Universal Plug and Play Device Host
Open your registry and find the key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\upnphost]. Set the value of "Start" to "4" to disable the service, or "3" to enable it.

Disable UnPnP Discovery Service
Open your registry and find the key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SSDPSRV]. Set the value of "Start" to "4" to disable the service, or "3" to enable it.

Is it right? Thanks for your attention to my question =)

Have a nice day!)

If no one has a better idea then, for Windows 7, I'd just stop the upnphost and SSDPSRV services following a reboot.

There's some C# code to stop a service programatically here (http://www.csharp-examples.net/restart-windows-service/).

To use the ServiceController class and ServiceControllerStatus enum, you'll need to add a reference to System.ServiceProcess.dll if you don't already have it. You'll also need this 'using' directive:

using System.ServiceProcess;
