I used to use this app all the time a few years back, and I thought I no longer needed it until yesterday.

Picture the scene: You have a pile of windows open, working on lots of stuff, some saved, some not. Suddenly, your PC locks up. nothing will respond. The mouse barely moves. Windows will not redraw. CTRL + ALT + DEL seems to offer help, but once you click on 'Task Manager' the whole process just repeats, and we lock up again.  So what do you do? Sit there and hope for the best? Restart?

Well if you've already installed ProcessTamer, this might not happen at all in the first place. Process Tamer simply watches for system processes (programs) which are hogging too much of the CPU and reduces their priority.

In the early days of Firefox memory leaks, I found this hugely useful. Ever since firefox 3, I haven't had a need for it. But yesterday, I downloaded a piece of software to interface with my Sony Ericsson phone which completely crapped out and hung my system. Only through patient clicking and waiting did I manage to kill the process, and even then it took over 10 minutes to do.

Process Tamer is a tiny piece of software, with a tiny memory footprint, which you may never have to use in your entire computing life. However, if you ever do need it, you'll be very thankful for it.

PS: Just an additional tip here, on the same subject. I've seen a lot of people complain that their system is running slow because something called 'System Idle Process' is at 99%. People wrongly assume that these are background windows tasks hogging all the resources. In fact, System Idle Process is a process who's only job is to keep the CPU running when nothing else needs it. I don't know the exact technical reasons, but the CPU needs to be kept working constantly, if not intensely. If you ever see System Idle Process running at close to 99%,
it means that your system resources are almost 100% available, and nothing else is using them.

Update:

Looks like I already posted about ProcessTamer back when I started this blog! Whoops…
