This article tells you how to setup the Windows 10 Login Screen so that it shows a list of users. This is especially helpful for elementary school computer labs, where students may have difficulty remembering and typing in both their correct username and password.
Step 1: Open the Registry Editor to do this Search: Regedit
In the Registry Editor click on the following:
Click on Enabled and change the setting from 0 to 1
Open Note Pad.
REG ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\UserSwitch /v Enabled /t REG_DWORD /d 1 /f
Save as UserSwitch.bat
Save this somewhere where the file won't be moved. For instance I wouldn't save this to desktop. I usually save this to the root of c:. It will work where ever you save it, it's just that if you delete or move the file the computer won't be able to run it.
Open Task Scheduler
Search Task Scheduler and click on the app.
Click on Create Task
For name call it something like Show all Users
Click Run whether user is logged on or not.
Click Run with Highest Privileges.
At the bottom click on Configure for Windows 10
Click on the Triggers Tab at the top, and press New.
Select Begin Task and At log in Settings: Any users Then Press Okay.
Click Actions then New.
Where it says Programs/Switch click Browse. Browse to your UserSwitch.bat program and click it. Select Okay.
Restart the computer.
Congratulations your multiple user accounts should show up in the lower left corner of your login screen.
