Windows: Lock the screen by command line

1 Comment

Hi,

there is no command line tool that can lock the screen, but it’s possible by calling the Win32 API function.
This can be done by Rundll32.exe

D:\> Rundll32.exe user32.dll,LockWorkStation

  1. FYI – Also if you want to run screen saver then lock screen via a one line cmd line. Good for using for shortcut key scripts.

    start /wait %windir%\SCREENAVER.scr & rundll32.exe user32.dll,LockWorkStation
