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:

HKEY_LOCAL_MACHINE

SOFTWARE

Microsoft

Windows

CurrentVersion

Authentication

LogonUI

UserSwitch

Click on Enabled and change the setting from 0 to 1

Step 2

Open Note Pad.

Type: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.

Step 3:

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.
