To properly lock a computer, the most common and secure way is to use a keyboard shortcut that instantly locks the screen and requires a password or login to unlock it. For Windows, the recommended shortcut is to press the Windows key + L together. This immediately locks the computer, keeping all open files and programs running but inaccessible until the user logs back in with their password. On macOS, the shortcut is Control + Command + Q. Additionally, for Windows, the computer can also be locked by pressing Ctrl + Alt + Delete and then selecting Lock from the options. Another method is to click the user icon in the Start Menu and choose Lock. There are also options in the power button settings to make pressing it put the computer to sleep and require login on wake. Manually locking the computer screen is crucial when stepping away to protect information from unauthorized access without shutting down or logging off. This action preserves the session and allows quick resumption by unlocking. In summary, the proper way to lock a computer is:
- On Windows: Press Windows + L keys together.
- Alternatively, use Ctrl + Alt + Delete and select Lock or use the Start Menu user icon.
- On macOS: Press Control + Command + Q.
Locking ensures security while keeping your session intact and is a basic best practice for data protection in both personal and professional environments.
