How to capture a screenshot?
Simply press Shift+Print Scrn. Press Alt+Print Scrn to get just a shot of the window you have open.
Then paste that image into some other program, like Word or Paint or whatever you need to use it in.

I really like the free program Screen Hunter 4.0. They sell one with more features but really the free one does what I need. Once you set it up you can click and drag around what you want to take a picture of. Plus you can hide the mouse and many more options. Check out it out.
