Hello. I have quite long Winlogon init phase, my monitor's dispay is black before the system shows me logon ui (after resolution is changed to native one), the blank screen holds for a quite time before system shows me its initial screen with clock in the lower left corner. https://docs.google.com/file/d/0B2-5mdG39PcAWWlhdzVlS0R4Rms/edit?usp=sharing - here is my trace with situation that matches the description above. What do I need to do to solve this problem? I would really appreciate help of this wonderful community. Thanks.
