Open Source Screen Shot Utilities for Windows

To help write some posts for this blog, I needed a free Windows screenshot utility. So Googling around a bit, this is what I found.

GreenShot - Installs as a System Tray icon in the lower right hand corner of your desktop. Screen shots can be taken by right clicking the icon or by using the PrintScreen key combinations. Files are saved in the PNG format by default. Simple and easy to use. I'm giving this a try right now.

I also found ZScreen but I haven't tried it yet.
