Whenever you leave your computer unattended, you can lock Windows and bring up the Ctrl + Alt + Del screen. If you want to prevent others from logging off your account, here are simple ways to remove the “Sign out” option from the Ctrl + Alt + Del screen in Windows 10.

Method 1: Remove Sign out from Ctrl+Alt+Del Screen via Group Policy

1. Open Local Group Policy Editor and browse to: User Configuration -> Administrative Templates -> System -> Ctrl+Alt+Del Options. In the right pane, double-click the “Remove Logoff” policy.

   

2. Select the Enabled option. Click Apply and then OK.

   

3. Close Local Group Policy Editor and restart your system. The next time you press the Windows + L key combination, you’ll see that the “Sign out” option is missing.

Method 2: Remove Sign Out from Ctrl+Alt+Del Screen via Registry Editor

1. Open Registry Editor and navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer. In the right pane, right-click the blank area and select New -> DWORD (32-bit) Value.

   

2. Name the new DWORD NoLogoff, then double-click it and change its value to 1. Click OK.

   

3. Close Registry Editor. After rebooting, you can check if the “Sign out” option is removed from the Ctrl + Alt + Del screen.

That’s it!
