Windows Boot PreSessionInit time up to 140sec Struggling to find reason

Question

Windows Boot PreSessionInit time up to 140sec. Struggling to find reason.

OS Name:                   Microsoft Windows 8.1 Pro
OS Version:                6.3.9600 N/A Build 9600
Processor(s):              1 Processor(s) Installed.
                           [01]: Intel64 Family 6 Model 58 Stepping 9 GenuineInt
el ~2101 Mhz
BIOS Version:              Insyde Corp. R0093C6, 8/22/2012
Available Physical Memory: 1,296 MB
Virtual Memory: Max Size:  21,478 MB
Virtual Memory: Available: 9,341 MB
Virtual Memory: In Use:    12,137 MB

followed this guide: Newish Windows 10 installation taking ~ 20 minutes in the pre session init phase

what I found is:

interval endTime="130463" startTime="0" name="PreSMSS" duration="130463"

however I could not find any driver that cause such a lag.

etl link: https://mega.nz/#!pmpByQ6D!SouVWRGd3tJQfLMO3XMmiJJBFf3OG5CrMKOqzmPP5-I

it seems like smth loops/waits after bootstart and before systemstart, but it lacks an information what exactly. (I don`t know how to profile it or find here in logs)

(any advise or a link for a tutorial will be much appreciated. Thanks.)

So in the summary you see that the PreSMSS subphase is slow:

What Happens in This Subphase The PreSMSS subphase begins when the kernel is invoked. During this subphase, the kernel initializes data structures and components. It also starts the PnP manager, which initializes the BOOT_START drivers that were loaded during the OSLoader phase. When the PnP manager detects a device, it loads and initializes the device’s drivers

Visual Cues PreSMSS begins approximately when the “Loading Windows” splash screen appears. There are no explicit visual cues for the end of PreSMSS.

In your case it is not a required device that takes too long, it is an driver that doesn't show up in this summary.

When you open the ETL, drag & drop the CPU usage (Sampled) to the analyze pane:

you see that System Process takes a high CPU usage for 130s at the beginning of the boot.

So you need the analyze the CPU usage of System process. In your case it shows that a Kaspersky Filter driver (klbackupdisk.sys) is involved:

Try to remove Kaspersky. Next I see BitLocker Drive Encryption Driver (fvevol.sys). If you have encrypted the Drive undo this and look if boot is faster.
