When someone says "desktop wallpaper", the first thing that comes to mind is a picture of a person, usually in a relaxing blue ocean setting. But if you're not familiar with Windows, then it's probably just a system tray icon. A Windows icon can be anything. Sometimes, a game or even a DVD file icon. But what the icon actually does is to help the computer tell the computer what the file is, and where it is. Because of this, most programs allow you to use an icon as a shortcut for the program itself.
There are many free applications that you can download off the Internet that work in exactly the same way. As an example, there is an application called Oceanis that you can download and use to create wallpapers for your PC. When you download this application, it's always recommended that you use a specific program to make sure that your downloads are safe. You don't want any damage occurring to your computer due to unsafe downloads. Another tip to remember when downloading free applications is that you always use a program that doesn't have spyware and malware on it.

The first time that you use it, you'll be asked if you want to use the program to create your wallpaper. Just follow the prompts, and you're all set!
