    It's weird ! don't see the post boot phase in the boot trace, and the Explorer init phase took ~2 min before the trace ends.

    What I've noticed though, is that explorer.exe process starts by running "App Readiness" task and waits 29s.

    Disable the App Readiness service and see if it helps ...

    Hallelujah!

    The background screen now appears immediately after the password is entered with no discernible delay.

    I admire your knowledge of the innards of Win10 and your deductive skills in applying them.

    I hope that if you should ever run into your own personal Waterloo situation that someone as helpful as you have been will come along to help you resolve your issue.

    You sir, are a credit to this community.

    Thank you...

    Hooooya.

    I'm glad to hear that. Thank you.

    Would you mind to upload another boot trace I'll look if we can optimize more.

    I know there are some people here interested in this technique.

    Now we can clearly see that the Explorer init phase duration drops down to 2s.

    Winlogon Init phase took 39s. But this because you waited 25s (from 9s to 34s) to hit the CTRL+ALT+DEL keys to enter your credentials.

    So for me, your system is now booting as it should do.

    I got same black screen issue perhaps caused by update KB4074588. Unfortunately App Readiness disabled didn't work for me and black screen 5 min continues after each boot. I did another post here last weekend in this forum, as I have another boot issue. Maybe @Kari could help, he is a Finn too and I'll send him a message for this thread
