In the location box, type or paste: rundll32.exe user32.dll,LockWorkStation Click , name it "Lock PC," and click Finish .

System sleep and lock timers are effective for unattended devices but do not serve the user who leaves their desk momentarily. This reinforces the necessity of the manual Win + L shortcut.

The 'L' serves as a mnemonic device for "Lock." This cognitive mapping reduces the learning curve for new users. The action becomes muscle memory rapidly, transitioning the user from a "conscious competence" state (thinking about the shortcut) to "unconscious competence" (performing the action without thought).

Windows 11 introduced features where the PC locks automatically when a paired Bluetooth device (like a smartphone) moves out of range. While this is a form of "shortcut" (bypassing user input entirely), it introduces latency. The system does not lock instantly upon separation; it waits for the signal to degrade, leaving a window of vulnerability.
