Change last logged on user on Windows 10

In Windows 10 you can no longer change the last logged on user in the registry like you could in Windows 7. Windows 10 requires the user's SID to be entered as well. Here's an updated guide.

In HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI, you'll want to change 4 entries:

  • LastLoggedOnDisplayName
    • Enter the user's full name, like Allan Jude
  • LastLoggedOnSAMUser
    • Enter the username, like SHORTDOMAIN\allan.jude
  • LastLoggedOnUser
    • Enter the username again, like SHORTDOMAIN\allan.jude
  • LastLoggedOnUserSID
    • Enter the user's SID, like S-1-5-21-112783954-3472839473-6329827380-1437
    • You can find the exact SID with wmic useraccount where name='allan.jude' get sid
    • Or you can search through the list of all users with wmic useraccount, and pipe it into Windows's version of grep, which I find easier to remember: wmic useraccount | findstr allan

Now you can log out, and you should be good to leave the workstation for the user.

Hm, seems to work for logging off. Any approaches for restarting the system?
