Windows 10 Logon takes around 40 minutes

Hi,

After entering my passwort, Windows 10 takes around 40 minutes to load my desktop. It appeared recently, so I assume it has to do with the 20H2 update.

I used the Windows Performance Analyzer to analyze my boot. However, I need some help interpreting the results.
I'll upload some graphs, let me know if someone could help me out or tell me if you need more images from the analysis.

Here you go

Section "Other" Boot phases


Section "System Activity" Processes


Section "Computation" CPU Usage (Sampled)

I see no obvious answer, I have never used that tool before, but in the 3rd window the vast majority of the time is idle, so maybe its waiting for a service or network connection to respond, but pure speculation on my part.

I do use WiFi and it is not connected when i login to my Desktop.

Could that be a problem? How can I find the cause if not with this tool?

Potentially yes, to rule it out, make sure its connected when you login.

1) How long does your PC take to reach the logon screen?
2) Did this PC work fine before updating to 20H2?
3) Did you upgrade online using Windows update or clean install while offline?
4) Have you checked the time required to boot to Safe Mode? If not, please test and report.

I did fill out the main things about my PC.

1) I takes around 10 seconds which is normal and has always been like that. But then when I enter my PIN the desktop loading takes about 40 minutes
2) Yes it did. However I installed all the necessary updates afterwards too, so it could be due to some KBXXX update as well.
3) Yes I used windows update and did the necessary updates. I did not use optional updates, however.
4) I need to try out safe mode later. Because it will take me another 40-50 minutes to start normally after I try out safe boot.

First, make sure all your drivers and bios are up to date.

If you share your boot trace maybe I can help you with that.

I got you with the .etl file. I uploaded it on mega.nz, it took a while since it is a 3 GB file.

Hopefully you can help out! Thanks for the effort.

You should compress it before you download it.
