If you are using keyboard without a windows key or would like a clickable command, you have another option to lock your computer. This can be done by using the command 'rundll'. Right-click in an empty space on the Desktop and select 'New -> Shortcut'. It will ask you to type the location of the item. Type 'Rundll32.exe user32.dll, Lock Workstation' in the dialog box. After that click 'Next' and insert a name, for example, 'Lock Computer'. Lastly click on 'Finish'. You can assign any icon to the shortcut. Now simply double click it to lock the computer.
