Locking your Windows 10 PC/MAC Computer is the best way to secure your computer when you step away. This won’t quit or interrupt any running applications, and you have to type your PIN or password to get past the lock screen.  Here are a few ways you can lock your computer screen.


  • Press the Windows Key + L

  • Lock Your Computer in the Start Menu
    • Click the Start button (the Windows icon), select your account name, and then click “Lock.”

  • Ctrl+Alt+Delete

    • The Ctrl+Alt+Delete keyboard shortcut is commonly used to kill unresponsive software, but you can also use it to lock your computer.

Press Ctrl+Alt+Delete, and then click “Lock” in the menu that appears.

  • You can set your PC to lock automatically when the screen saver pops up. Go to Control Panel > Appearance & Personalization > Change screen saver and then check the box for On resume, display logon screen. You can also set a time for how long your PC should wait before starting the screen saver. Now, when you exit out of the screensaver, you’ll need to enter your system password to get back in.
