Hanging on Windows Shutdown

[TechSupp]

Probably a driver issue but just imaged a Samsung N130 and all seemed Ok, all working, no crashes etc, added the new network drivers etc but now on shoutdown it hangs for ages at the Windows is Shutting down screen but eventually shuts down as normal. How can I best try and sort this out. Its not connected to the network as yet so thats not the problem (well ist picked up the wireless connection bu t its not set to logon etc or run profiles as yet as this is the master image for the next batch so I want to try and get it right.
