There's also a bunch of dedicated screenshot tools for many of these operating systems, so they've been noted as well. Whatever your device and OS, we should be able to help you take a screenshot today.

Windows Screenshot

Windows has a simple, yet inelegant way of dealing with screenshots. Simply click on PrtScn and you'll have the screenshot saved in the clipboard. Then open your favourite picture editor and paste the image into a new document.

For instance, MS Paint and Gimp are free image editors that work well.

Android Screenshot

If you're using ICS (Android 4.0), getting a screenshot is no problem. Just press and hold the Volume Down and Power buttons at the same time and the screenshot will appear in your Gallery.

However, if you're using an older Android release, things get much trickier. Certain models of phone have screenshot capabilites built in, such as several of the Galaxy phones, but everyone else will need to either use the Android SDK method or root their phone and get a dedicated application.

To take screenshots using the Android SDK, you'll need to install the Android SDK on your computer, then connect your Android. Using the DDMS application, you then choose Device > Screen Capture.
