I installed windows 10 enterprise from a DVD. Now the boot takes to long. More specific the "Session Init" phase is idling for about 80 seconds. The ETL file for WPA can be downloaded at https://drive.google.com/open?id=0B3f_WdRCKIHWRmxJU0VjQjM1WFE

I would be very thankful for some help with finding the cause for the 80 seconds because I really don't know how to use the analyzer.

Thanks Heiner


When you look at the services graph, you can see that the LSM ( Local Session Manager) service takes 71s to init:

This is causing the delay.

The svchost.exe (720) is waiting for some WorkerThread. Contact the Microsoft Support and send them the ETL. They can analyze this deeper.


Thank you very much. I was able to narrow it down further. It was the ULPS feature of the display driver display driver that caused this. My solution is to disable ULPS as described here: https://community.amd.com/thread/176003

This solution isn't perfect, but it's good enough for me.

As far as I am concerned this is closed.


  • this is an interesting solution. I never heard about ULPS and can't see any AMD related calls. – magicandre1981 Jan 19 '17 at 16:18
