Just press the Windows key and the letter "L" in the bottom left corner of the keyboard at the same time, and the screen will immediately turn off, enter a lock screen state, and return to the login interface. You need to enter the correct password or perform authentication to unlock it.
In addition to shortcut keys, Windows users can also lock their screens in other ways, such as:
Click the "Start" button in the bottom left corner of the screen, find the user avatar or lock icon in the pop-up menu, and click to lock the screen.
Press the "Ctrl+Alt+Delete" key combination to enter the security window, then press the "Alt+K" key or directly click the "Lock Screen" button to lock the computer.

The specific method is to right-click on a blank space on the desktop, select "New/New Shortcut", and then enter the lock screen command (such as "rundll32", "exe user32", "dll", "LockWorkStation") to complete the creation of the shortcut. Afterwards, you can set a shortcut key for the shortcut, such as "F2", so that you only need to press that key to lock the screen. summary
