Microsoft has added two new versions of its stripped-down Windows XP Starter Edition operating system.
The company said on Tuesday that the software is now available in Arabic and Turkish editions for sale in Egypt and Turkey.
Starter Edition is a critical part of Microsoft's attempts to grow sales of Windows in developing countries. The software is already offered in Thailand, Malaysi, Indonesia, India, Brazil, Mexico and Spanish-speaking Latin America.
In July, Microsoft said it had sold 100,000 copies of Starter Edition.
