You can also lock a PC via a bat file:
This is similar to a Windows shortcut method. But it’s a DOS version. If you’ve never created a bat (batch) file, but would like to try this method, simply open a new text file (such as with Notepad) and type the following commands:
rundll32.exe user32.dll, LockWorkStation
Save the file with a .bat extension, such as Lock.bat, and you’re done. Double click to make the file run.
