PCLock

PCLock is a simplistic and straightforward application that locks your computer, permitting you to step away from the desk while knowing that no one else can gain access to your PC without your permission.

Lock your computer using this app instead of Win+L

It works just like pressing Win+L on your keyboard, and it comes in handy if your Windows has some issues and the key combination doesn't trigger this command, or if you simply want to lock the PC by double-clicking an icon or from the command-line interface.

Just download and open the file

The PC locker doesn't require setup. It's packed in a single executable that you can copy to a preferred folder on your hard disk or store to a thumb drive to seamlessly launch PCLock on any workstation with minimal effort on your behalf. It doesn't make any changes to the system registry or create additional files on the HDD without letting you know about it.

Double-click the file or lock the PC from Command Prompt

The computer gets locked as soon as you double-click the program's file, so there is no graphical interface involved. However, you can also call PCLock's process from Command Prompt or another preferred console tool, by entering the file name and extension.

Pin the file to your taskbar for quick access

There are no command-line arguments available. If, by any reason, the task fails, the computer locker returns zero in the console window.
Because PCLock can be used by double-clicking its file, you can pin this file to your taskbar or place it on the desktop to be able to rapidly lock the PC when preparing to leave it unattended.

Simple PC locker with CMD support

All things considered, PCLock delivers a fast and uncomplicated solution for locking your computer when the Win+L hotkey fails to do so. This can be done by double-clicking the program file or by calling its process from a console interface.
