Windows XP Starter Edition build 2600.2901

This build is the Windows XP Starter SKU, based on Service Pack 2 of Windows XP Home. It is a stripped down version of Windows XP Home that was only released internationally for low-cost or low-end PCs. Unlike its Service Pack 3 SKU, it uses its own build number.

Differences

 * The Luna theme cannot be activated since the tab to change the theme is removed. However, the file is still available and can be used via registry modification.
 * The user cannot run more than three programs or three sessions of a program. Terminating explorer.exe may bypass this though.
 * This build will not boot on a computer with more than 512MB or on a faster CPU.
 * A permanent watermark is added on the bottom right of the screen, which will still appear on top of everything as long as explorer.exe is active.
 * It uses large icons and mouse cursor by default.
 * There is only one wallpaper that is used by default. However, international releases appears to have different backgrounds.
 * It contains a very different File Protection, if there is any user modification in the registry or a few system files, then an "Unsupported state" error message will appear and then  will get terminated, more than likely leading to a system crash.
 * Classic View in the Control Panel is missing.

Apparently, there is also an 1024×768 screen resolution limitation, but this is not implemented.
