Applicable to all users, especially those in internet cafes or users who leave their computers on while gaming!
Double-click to open the file, and you will see a password input bar (the password is freely set by you; you need to input the password twice, and both inputs must be consistent). After entering the password, press "Lock" (Be sure to remember the password you set, otherwise, you won't be able to unlock it later. You may not know whether restarting will work or if you need the original password. Remember: You must remember your password!). After pressing "Lock", the computer will be successfully locked. Moving the mouse or pressing keys on the keyboard will be invalid. The screen will only display "My turf, my rules" and "Unlock". If you want to unlock it, click the "Unlock" button on the screen. A numeric dialog box will pop up where you can enter the unlock password. After entering the correct password, press "Unlock" in the dialog box to unlock the system.
Admonition: Everyone must remember the password they set!
