According to Walter Bender, president of Software and Content at OLPC, there is no agreement in place between OLPC and Microsoft to offer XO laptops with any version of Windows. Bender also indicated that Microsoft has not contacted OLPC regarding its $3 software bundling program, nor have any governments requested that the XO be outfitted with Windows. In short, there is no existing collaboration between Microsoft and OLPC aimed at outfitting the XO laptop with Windows.

“We are a free and open-source shop. We have no one from OLPC working with Microsoft on developing a Windows platform for the XO. MS doesn’t get any special treatment from OLPC,” Bender told Ars.
