Screen capture

Screen captures are useful for most computer users. You might need to show a screen to someone for help, or to include a computer screen in a report, or just to keep a hard record of something you saw in your computer.

In Windows you can capture the screen using the "Print Screen" key. Just press it and then you can paste the image into any program capable of handling graphics. Also, if you want to capture just the active window, use "Alt" + "Print Screen".

If you want to automate the screen capture task or have additional control, I strongly recommend the Greenshot tool. It's very simple and very effective. And it's also open-source and free!

Also, since Vista, Windows also includes a snipping tool.

To complete the topic of screen capture, I also use the ScreenGrab Firefox extension. It's especially useful if you want to capture a complete web page, without having to scroll the window.
