Process Liquidator is a task manager-type program which focuses on making it quicker and easier to view and delete your running processes.
Once running, for instance, there's no hotkey or icon clicking required to launch the program. Just move your mouse cursor over to the right edge of the screen, and the Process Liquidator panel will slide into view.
This is essentially just a lengthy list of running processes. Scroll it, click on one of interest and you'll see more about it: the process ID, whether it's 32 or 64-bit, its owner, domain and so on.
Terminating a process is as easy as right-clicking it and confirming that, yes, you really do want to do that.
And there are lots of configuration options, too. You can tweak how Process Liquidator is launched, its colour scheme, docking position (left or right side), how you want to delete processes (single left click, single right click, double-click, delete key), whether you want to be warned before deletion, and more.
What you don't get here is a great deal of power. The information displayed on processes is fairly basic, for instance. And the process termination method appears to be entirely standard (don't expect to be able to terminate protected malware, for instance).
And so, essentially, the value of the program is in the way you can launch it just with a mouse movement, and then kill a process in a couple of clicks. If that matters to you, take a look; if not, stick with Task Manager, Process Explorer or your other preferred process manager.
