To lock a laptop screen quickly and securely, the most common and easiest method for Windows is to press the keyboard shortcut Windows key + L. This instantly locks the screen and requires the user password to unlock it afterward. Alternatively, one can use Ctrl + Alt + Del and then select Lock from the menu. Other methods include:
- From the Start Menu: Click the Windows logo, click the user icon, then click Lock.
- Configuring the power button to put the computer to sleep and lock it.
- Using shortcuts or tools like creating a desktop shortcut with the command
%windir%\System32\rundll32.exe user32.dll,LockWorkStation.
For Mac laptops, the shortcut to lock the screen quickly is Control + Command + Q , or using the Apple menu to select Lock Screen. These methods allow secure locking without shutting down or closing applications, ideal for when leaving the laptop unattended briefly.
