Screen Capture in Windows 7 for demos

I often have to do screen capture for demos. There are 3 different ways you can capture screen images in Windows 7. Two of them come with Windows 7. Third  one needs Microsoft Expression Encoder which is not free.

1. Using traditional PrintScreen method. Either you can use PrintScreen button which will capture the entire screen or use ALT PrintScreen to capture the active window. Then you have to copy it to a program like Paint. Take a screen capture (print screen)
2. Using the Snip tool. This is a cool feature. Type snip in the Start programs. You can use the snip in 3 different modes. I use the rectangular mode to capture portion of a screen, for example Windows Phone 7 emulator screens. It automatically produces a JPEG image which you can save. Use Snipping Tool to capture screen shots
3. Expression Encoder. This is a powerful tool which you can use not only for capturing static images, but also videos of actual demos.Expression Studio
