Lock PC Professional

Lock PC Professional is a small software application designed specifically for helping you lock your computer while you are away in order to make sure unauthorized users cannot have access to your private information.

Simple looks

There’s not much to brag about the user interface as everything is kept as simple and clear as possible. The tool embeds only a few dedicated parameters that you can play with.

How it works

In order to block access to your screen, you are required to set up a master password. Additionally, you may change the password, provided that you have specified the correct one.
When you leave your computer unattended and activate the lockdown mode, the tool automatically disables hotkeys, including Ctrl+Alt+Del, Alt+Tab, or other combinations. You cannot open the Task Manager and access you system without providing the correct password.
It is important to mention that the program is configured to automatically run at Windows startup, so restarting or shutting down the computer doesn’t help intruders to bypass the blocking mode.

Performance

Tests revealed that Lock PC Professional accomplishes a task pretty quickly and without errors. It doesn’t eat up a lot of CPU and memory, so the overall performance of the computer is not affected.

What it lacks

On the downside, Lock PC Professional doesn’t offer support for any customization options that could help you change the background image or color and send email alerts each time a user tries to gain access to your PC.

Bottom line

All in all, Lock PC Professional proves to be a straightforward piece of software that focuses solely on blocking other users’ access to your desktop, so it doesn’t provide support for customization features.
