Hmm.. but there is a clear difference in the times in the captures. One is 189 seconds, and the other is 269 seconds.
That does not match with the 3 min difference, but at least one shows longer boot than the other.
Is there something I can add to the trace options to give a better trace?
The only long boot phase in the trace is the Post-boot phase.
This phase occurs after you open a session and desktop is displayed.

In this phase windows starts services, auto-startup programs, scheduled tasks ...etc.

So if you experience a delay in this phase (Ex: your session is sluggish) try to:
* disable non-MS services and auto startup programs
* disable unneeded scheduled task if any.
