How Do I Change the Wallpaper on an Asus Mini Laptop?

Upgrade your Operating System
There are four different versions of Windows 7: Starter, Home Premium, Professional, and Ultimate. Windows 7 Starter is only packaged with netbooks, such as the Asus Mini, and contains several restrictions on the operating system's functionality, one of which is a restriction on changing the desktop wallpaper.By far the easiest and most legal way to enable the desktop customization functionality is to upgrade your netbook to Windows 7 Home Premium. You can buy the upgrade on Microsoft.com for about $80.
Use the Starter Wallpaper Changer
While there are programs on the Internet that will enable you to change your Asus Mini's desktop wall paper, it is important to read your End User License Agreement (EULA) to ensure it's OK before using these programs. Microsoft may be entitled to legal damages if you use programs such as the Starter Wallpaper Changer in violation of the agreement you signed when you purchased your computer.To use: Download and the Starter Wallpaper Changer (see “Resources”), then double-click to open. Say 'Yes' to any security alert that pops up and install the program. When finished installing, the program will display a dialog box asking for the path to the picture you'd like to set as your background. Click 'Browse' and select your preferred picture, then press 'OK.' Click 'Apply' to change the wallpaper. Then restart your computer.
