Since some time now I have a huge boot delay problem in Windows 7 64bit. It appeares to be in the Winlogon init Phase. I used xbootmgr to trace the cause of this and a summary of the boot phases shows: Problem is that during the delay the display is black. So I don't know what the computer is doing. The harddisk light flashes at regular intervals of about 1 sec. There are no recorded events and no driver delays. Resuming from sleepmode takes an equally long time. A reboot however does not! Since I have an SSD as system disk a reboot really flies! I'm stuck. Any thoughts or help on this would be greatly appreciated.
