WIndows SessionInit taking way too long on cold boot

I'm experiencing issues with my laptop.

Config :

• Dell Latitude E6430
• Intel i7-3630QM
• 8GB RAM
• 256Go Kingston SSDNOW V300 SSD

Pretty much all informations we need here

Since I upgraded to Windows 10, I'm experiencing a very long cold boot time (when I use Restart, fast startup being enabled, the problem doesn't occur)

Here are the graphs I extracted from the trace :

The trace can be found here :

I tried to format and reinstall, the problem comes back after a few minutes (while installing drivers). I haven't yet found which one. I will resume my investigations when I get back from work but in the meantime I ask to you. Thanks

In the generic events tab in the Microsoft-Windows-Kernel-PnP provider data, you see that starting the device with the hardware ID of PCI\VEN_8086&DEV_1E3A&SUBSYS_05341028&REV_04\3&11583659&0&B0 takes 30s to start:

The Id belongs to Intel(R) Management Engine Interface

which is only a enterprise feature and normal home users can disable this device in device manager.
