Find Lock all taskbar settings. Open its properties. Change the setting to Configured.
If this setting is Enabled, the user is prevented from changing the taskbar settings via the Taskbar Properties dialog box. Enabling this setting prevents the user from accessing the taskbar control panel, unlocking, resizing, moving or rearranging taskbar items.

You may need to restart explorer.exe or your computer for the setting to work.
