Have you ever wondered why your startup is slow? I assumed you noticed the new event viewer, but have you noticed the Applications and Services Logs, also try to turn on the View > Show Analytic and Debug Logs..
To our goal, have a look at slow startups.. Have a look at this log: Applications and Services Logs\Microsoft\Windows\Diagnostics-Performance\Operational.
Have a look at the event id: 100 for Startup, 200 for Shutdown, 300 for Standby.
Open an event with event id 100 and it could look something like this:
You can clearly see that you this startup took 321482 ms just over 5 minutes. Press details too have a more detailed information about every step in the startup sequence. Too see what too longer time than usual have a look at the event with event id 101..
You could also try my PowerShell script that will gather the information and summarize it for you.
