Does it make a difference if you disable the WLAN with the switcher at the laptop, boot Windows and after Windows is fully booted, enable the WLAN again? Do you still have delays? The trace still shows that the LanManagerservice is still slow. Have you really disabled the service? to see why services.msc opens so slowly you must run Process Monitor in background: http://technet.microsoft.com/en-us/sysinternals/bb896645 and after services.msc is shown, stop Process Monitor and look at the duration column in "Process Monitor" to see what takes most time.
