Today, Microsoft Corp. and One Laptop per Child (OLPC) announced an agreement that will make the Microsoft Windows operating system available on OLPC’s low-cost XO laptops for the world’s poorest children. Through this agreement, trials of the XO running Windows are planned to begin as soon as June in key emerging markets. Recognizing that the challenge of providing high-quality education for children in the developing world is too large to be solved by any single organization, Microsoft and OLPC are committed to working with governments and nongovernmental organizations to ensure the success of these pilot programs.
