A free app for Android, by MALGOW.

Win XP Simulator is a game that lets you use your Android device as if you were using a Windows XP machine. It lets you run all the apps that you can normally install on a Windows XP machine, even ones that don’t normally work on Android. You can even use the Windows XP icon and theme.

The game is based on a desktop-like interface. It has a start menu, an icon bar, a taskbar, and a desktop. You can even drag and drop items between the various bars. It has a built-in anti-virus program that will scan your apps for viruses and remove them. You can also use it to remove any viruses that are on your device.
