There are several different ways you can lock your Windows 10 PC like the Windows key+L keyboard shortcut. If your Windows key is broken but you still want a quick way to lock your PC, create a desktop shortcut.

First, right-click anywhere on the Desktop and a menu will appear. Here, hover your cursor over the "New" option and then select "Shortcut" from the submenu.
