From USA Today (link):
Lenovo, China’s No. 1 PC maker, on Monday said it plans an aggressive program to pre-install Microsoft Windows on PCs sold there.
Last year, less than 10% of Lenovo PCs sold in China came with Windows, Lenovo Chairman Yang Yuanqing said in an interview Monday. After Lenovo launched a test program with Microsoft in December, the number jumped to 70%, Yang says. The enhanced partnership announced Monday should cause that trend to continue, he says.
Yet Lenovo and Microsoft are releasing almost no details about their deal, saying only that Lenovo plans to buy $1.2 billion of Windows software over the next 12 months for PCs worldwide. (They won’t say how much Lenovo spent during the previous year.)
