One of my customers pointed out a really odd issue they're seeing on the login screen/lock screen on their machine. They have two 'personas' that correspond to them
- One persona is listed as LastName, FirstName and they can only login using PIN, Fingerprint, Face but not password.
- The other personal is listed as DOMAIN\Username and they can only login using password, not PIN, Fingerprint or Face.
- They also have two 'Other user' options
Here's a screenshot of what it essentially looks like
Again, it's the same account but for some reason there are two icons for it. I've confirmed they only have one user profile on that machine so it's not something wonky where a separate .000 user profile was created. (I double checked %SystemDrive%\Users, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileGuid and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList to be sure)
First of all has anyone ever see something like that?
Second, my customer tells me that when they initially got their machine everything was fine. However after restoring data from a third-party app we use to backup/restore user data & settings, this reappeared. Is there anything in the user profile (be it at the file level of the registry) that would allow a user to manipulate the login screen/lock screen?
Any feedback is greatly appreciated.
