I have 3 users on my computer using Windows 10. One of them recently became slow to login (6 seconds instead of 2). I looked in event viewer and both users have the same history when loging in. It seems that the winlogon is slower with one user (slow when showing "welcome").
Is that possible to profile what winlogon is trying to do? Are there more specific logs I can check? Thank you.
edits: It looks like the problem is caused in part by explorer.exe (thank you magicandre1981) since when I change the shell to something else, the problem is no present. I tried to disable some explore.exe extensions but not all of them. Maybe I should try to disable all shell extensions. I will also try with explorer.exe from an older Windows version (if there's no security against that).
I tried autoruns too and both users (slow and fast) have the same config. When I disable everything, the problem is still present.
This is not a domain-joined user nor a roaming profile. It's a just a regular local profile.
I only experience the slow login on that user when it's the first user to log in after boot. If I log with another user, then I logout and login with the slow login user, the issue is not present.
