LockPC

LockPC is a small Windows application designed with a single goal in mind: to help you lock your screen with the aid of a preset hotkey combination.

The advantages of being portable

Since this is a portable program, it is important to mention that it doesn’t leave any traces in the Windows Registry.
You can copy it on any USB flash drive or other devices, and take it with you whenever you to need to lock your computer on the breeze, without having to go through installation steps.

Plain looks

LockPC doesn’t offer support for a user interface in order to help you trigger the locking process. It only displays a dialog that asks you if you want to secure your desktop or not. Each time you want to lock your computer you have to go through the same process: run the EXE file and confirm that you want to activate the lock mode.
During the lock mode, the program displays the following message “Computer Locked. To unlock press the following keys: Ctrl+Alt+Del.” It doesn’t hide your desktop icons and running applications, so it only blocks your mouse and keyboard input.
On the downside, the utility reveals in the lock message which hotkey combination needs to be pressed in order to disable the process, so users may easily bypass the process and steal sensitive information.

Bottom line

Taking into consideration that users can easily bypass the lock mode and have access to your private data, you cannot rely on this application for blocking access to your screen. However, it proves to be quite useful especially when you want to leave your children in front of the computer tapping on the keyboard or performing random mouse clicks.
