One of the most useful utilities that I have been using for a couple year is ScreenHunter 4.0 Free. This tool installs easily and doesn’t require admin privileges to install. ScreenHunter is very easy to use and it allows to you create image files from any portion of your computer screen. I find it most useful for capturing regions of the screen and saving them directly to the clipboard to my choice of file formats.
Although it is free, watch out as you follow the links to download it. You don’t need to subscribe to the newsletter or give any information. If you have trouble getting to the Download site click here to go to it directly. Scroll down past the versions that cost to the free version.
