Process Blocker is a lightweight software application built specifically for helping administrators block programs based on a custom list.

It comes in handy especially when you want to make sure your children don’t spend too much time chatting with their friends using instant messaging utilities and playing games or you need to prevent your staff from using any unwanted program.

There is not much to brag about the user interface, as it sports a clean layout. Everything is kept as simple and clear as possible, so there are only a few configuration settings that need to be tweaked.

Process Blocker gives you the possibility to create a custom list with the programs that you want to block. You may add multiple items, edit or rename them, as well as enable or the disable the blocking process with just one click.

The tool offers support for the EXE, SCR, and COM file format, and lets you select the items that you want to block. Files can be added in the working environment using the built-in browse button, so you cannot rely on the drag-and-drop support.

You may insert the full path or name of the executable file (wildcard and environment variables are allowed), and block other applications with identical CRC for preventing utilities from running even if the executable file is renamed or moved. Plus, you may block items by user or group, and create exception lists.

When it comes to configuration settings, you can make the tool automatically log the blocking activity and save the TXT file to a custom folder and display system tray notifications when listed utilities are restricted.

During our testing we have noticed that Process Blocker carries out a task very quickly and without errors. It leaves a minimal footprint on system resources, so the overall performance of the computer is not hampered.

All in all, Process Blocker offers a simple yet efficient software solution for helping you block certain applications on the breeze, and is suitable for rookies and professionals alike.
