Rain OS is a simple operating system. To open a program simply click on it's icon. To close a program click on the X. The program with an arrow pointing down is the dowloader. The program with the green squigly lines on it is the antivirus program (A Trojan is a bad virus). The program with the magnifying glass is the Explore! game.(I made this on my old account, and found it again, so I posted it!)
