There is a such a secret feature in Windows 7. It is called PSR (Problem Steps Recorder). This feature helps you to give a program tutorial to your friends in a simple way. We don't need to use a PrintScreen to adding pictures in our tutorial presentation. These are the steps:
Start --> Run --> type: PSR then press Enter
and then the program will be launched as you see in a picture below
Just simply click on "Start Record" button to start saving your steps and click on "Stop Record" to stop saving.
I've just revealed a great tool in Windows 7, now you can try further by yourself.
