of course I ask the help of @zinou,
This is a clean install of windows 11, I am wasting a lot of time at boot on a rig that shouldn't have issues in general let alone at the logon screen
I've tried to analyze the .etl file but I can't understand what's causing the issue so I'm here asking for help

I found the problem for me was one of my hard drives attached by USB to my PC. Remove any USB devices one at a time to see if one is playing up. Going to try the drive in a new enclosure to see if that fixes it.

I don't use usb drives, only ssd, also no disc activity in the .etl

Do you mean at the login screen or from boot up generally? On my unsupported 10" netbook (!) I find it boots to login extremely quickly but hangs at the login screen for some time until entering the desktop. I'm putting that down to it being unsupported hardware basically - an atom processor and only 2gb ram - so I don't mind. On the core i7 5th generation uefi laptop (8gb ram) everything is very fast at boot up and login.

it's roughly one minute, I can see the 45 seconds for the winlogon init but I'm unable to follow the stack to something useful

So you notice that the delay occurs after the logon?
I can see 43s of delay after you enter your credentials. is this where the delay occurs?

the account is set for autologin, I disabled windows hello and used the old control userpasswords2 method, it's a microsoft account.

I only get to see the login animation with the spinning circle for something around those 45 seconds before the desktop appears
the stack tells me nothing

and that svchost.exe(4736) even less:

My guess is that the issue is may be related to the network.

Are you using a Microsoft account to log in ?
Have you tried to log in with a local account and see if it's faster?

I saw that you mentioned in your previous post that you are using a Microsoft account;
So yeah, create a local user account and log in with that account and see the difference.

just tested it this way:

- after creating a new local user (without deleting the ms account, can't do that now for various reasons) . Removed autologins and rebooted, blackscreen until the login prompt but after picking the user (whether it was the ms account or not) desktop came almost immediately
- set autologin for the local user, no changes still slow

created another .etl in this scenario and it's almost identical to the one I've already posted.

can you group CPU usage time by 'timeline by process, thread' ?
does it give you some insight?

If I do understand; when you disable the autologin the boot is faster?

it's faster only after the prompt appears on screen
before that it's just a black screen for those 45 seconds

Can you take a boot trace, while disabling the autologin? it may give us another perspective!

Check the "Network IO activity and the Registry activity"

I Do not see anything interesting in the network or the registry graphs!

what I suspect is the graphic card driver, for two reasons;
You said that you see a black screen during the login => There was similar cases were the graphic card was the culprit.

during the waiting period, I notice the dwm.exe (Desktop Window Manager) process running => dwm is the process that renders the desktop.

I think your AMD Radeon driver is at the latest version, so no update is possible for now!

what you could test to prove this theory, is to restart in the safe mode and see if the login takes the same time!

happened only a few times without autologin. with it enabled I can see the spinning wheel for the whole delay
anyways, today amd and microsoft released a couple patches to fix some bugs with amd products, so far I'm booting straight to desktop without issues..only booted up twice today, I'll keep it under observation and report
