A single user Windows 10 machine is starting and showing the logon screen only for a different user and asks for a password.
The user it shows is on the local network but does not use a password, even on their own machine. So I cannot get to their desktop.
The user who uses the machine (who had been showing up on the start screen) is not on the start screen. I can see their user files in C:\users.
Judging by dates on folders and files indicates the machine probably did a windows update a couple of days ago.
