Restore the Windows settings through LockDown Browser itself, because an interrupted or forced exit can leave the Windows security and power options restricted.
Restore the missing options
- Save your work and completely power off the computer.
- Turn it on and sign in to your personal Windows account.
- Open LockDown Browser and allow it to reach your school’s login page.
- Close LockDown Browser normally.
- Sign out of Windows—do not select Restart:
- Press Windows key + R.
- Enter the following command and select OK:
shutdown /l
- Sign back in and test:
- Ctrl+Alt+Delete should again offer the applicable security options.
- Start → account picture should show Sign out.
- Start → Power should show the normal power commands.
Respondus also documents a LockDown Browser /restore method that should display a Settings Restored confirmation.^1^ The recovery procedure and command-line sign-out workaround are summarized here as well.^2^
For future sessions, exit LockDown Browser normally before signing out or shutting down. Avoid another hard power-off unless the computer is completely unresponsive.
Use the correct Windows menus
Windows 11 does not necessarily place every account and power command directly on the Ctrl+Alt+Delete screen:
- To sign out, select Start → account picture/Accounts icon → Sign out.
- To switch accounts, select Start → account picture/Accounts icon → More, and select the account.
- To shut down or restart, select Start → Power.
- Alternatively, right-click Start → Shut down or sign out.
Signing out closes the current session and its applications; locking leaves that session running.^3^
If the school account is still absent
Treat this separately from the missing logout commands:
- Sign out using
shutdown /l. - On the sign-in screen, look in the lower-left corner for the school account.
- If it is absent but Other user appears, select it and enter the school account credentials. Microsoft documents Other user as the route for an account that is not listed.^4^
- If neither the school account nor Other user appears, contact the school’s IT or LockDown Browser support. Do not disconnect the school account from Settings → Accounts → Access work or school, because that can remove organizational access rather than restore the missing menu.
If only “Lock” remains after restoration
A Windows policy may still be active. Microsoft documents that the Remove Logoff policy removes logoff from Ctrl+Alt+Delete, while disabling or leaving that policy unconfigured restores it.^5^
On Windows 11 Pro, Education, or Enterprise:
- Press Windows key + R, enter
gpedit.msc, and press Enter. - Open User Configuration → Administrative Templates → System → Ctrl+Alt+Del Options.
- Open Remove Logoff.
- Set it to Not Configured, apply the change, and sign out with
shutdown /l. - Also check User Configuration → Administrative Templates → Start Menu and Taskbar → Remove Logoff on the Start Menu; set it to Not Configured if it was enabled. Microsoft documents that Start policies can separately hide Sign out and Switch user.^6^
If this is a school-managed computer or those settings revert automatically, stop there and ask school IT to remove the policy. Avoid manually deleting registry values unless the device is personally owned and the LockDown Browser restore procedure has failed; incorrect registry changes can affect sign-in and system controls.
