So this issue has been going on for almost a month now,event viewer is showing tons of these errors,i have 3 windows 10 installations and in each the error is there.Even tried to do a clean install on my main pc today to see if it would go away but to no effect.

    I also suspect the February batch, as it is when my trouble started, as i see in the log.

    I did try all of that and nothing worked.

    Today i did upgrade to Windows 11, but still the same autopilot.dll error is there.

    I might need to erase the disk and re-install, if things get worse.

    I have tried near all fix suggestions except for a clean W11 re-install, because I see others have tried and still have the issue. Common Windows fix this and Windows Hello for Business bug that many also face......

    FIXED

    It wasn't working, as “Microsoft Account Sign-in Assistant service” did not exist,

    Then i upgraded from Windows 10 to Windows 11, keeping my files.

    And voila there it was “Microsoft Account Sign-in Assistant service”, where i changed the properties and there was the happy ending.

    WARNING

    Users who try this workaround and disable their Microsoft Account Sign-in Assistant service may experience serious side effects afterwards.

    The 22-Sept-2022 TheWindowsClub article Autopilot.dll WIL Error Was Reported in Windows 11/10 where this workaround was first suggested warns that " This sign-in assistant utility facilitates users in signing on to several Microsoft apps*...note that if you are using the Outlook Calendar, Phone Link app, etc., then* those apps will not be able to connect to your account."

    The batcmd.com article at Microsoft Account Sign-in Assistant - Windows 10 Service also warns that "If this service is stopped, users will not be able to logon to the computer with their Microsoft account."

    Sure and obviously i am not using those services, i should have mentioned, and this is why this solution did work in my case.

    Thank you for adding this warning.
