So for some reason my boot is taking forever, like 353 seconds. I used xbootmgr to trace what is going on but I am not an expert. Can someone take a look and let me know what is taking all the time?

  • any update on your issue? – magicandre1981 Sep 5 '17 at 14:17
  • Thanks for the reply I would not have been able to find the issue without your help. I am trying to track down why the registry is not initializing quickly. I have attempted to 'clean' the registry with CCleaner but so far it has made no difference in boot times. Interestingly, I cant find anything on the web about the InitializeRegistry command so its tricky to figure out what is slowing it down. Interestingly, I backed up my system and then did a 'reset' and that fixed the problem, so at least I know it is not a hardware problem, but when I restore the system the problem remains. – DIY Dan Sep 5 '17 at 14:29
  • share a new trace, this time use WPRUI.exe, here the wait data are included in the trace when you select CPU. maybe I see what causes the delay – magicandre1981 Sep 5 '17 at 14:32

  • have you used the windows 10 compression on the 850 Evo SSD to get more space? I see the WOF.sys involved a lot (Wof.sys!FileProvReadCompressed). Also do a defrag of the SSD, this is sometimes good, your SSD is fragmented with 17%. also remove "Acronis Virtual Disk Storage Filter" (vidsflt.sys) and look if improves boot. also clear old restore points, I also see volsnap.sys calls – magicandre1981 Sep 6 '17 at 16:09

Looking at the ETL with Windows Performance Analyzer (WPA.exe) shows indeed that SMSSInit/Boot-SessionInit-Phase is taking the longest time with 211 seconds:

Drag & drop of the Generic Events graph shows that the that the task InitializeRegistry is the slowest part:

Make a full backup and try a registry cleaner tool (which I normally wan't recommend, but try it).

Solved. It was the Marvel 91xx SATA 6G Controller driver.I used the free version of Driver Easy to scan my system and it found that driver was out of date. As soon as I updated it my reboot time went down to 30 seconds, 20 of which are consumed between POST and the Windows icon, once I see the windows icon it takes less than 10 seconds before I see my desktop.
