Meanwhile, Google has reached only 27 percent of the online Chinese population, while Microsoft’s own Bing has penetrated less than 2 percent. It’s Microsoft’s newly announced partnership with China-Baidu though that will help Microsoft tap into over 600 million active Baidu Internet users.

China is high on Microsoft Corporation (NASDAQ:MSFT)’s list as a key target market for Windows 10.

Wednesday’s announcement comes on the same day China President Xi Jinping plans to visit Microsoft’s Redmond campus. The company also says it has struck a deal with the China Electronics Technology Group to provide localized Windows 10 versions to government-owned organizations and enterprises. He has used the trip as a chance to strengthen U.S.-China business relationships, inviting top CEOs from both countries to meet to talk about how they can better work together.

Now, customers from China can upgrade the official version of Windows 10 from Baidu’s distribution channel, “Windows 10 Express”.

There are over 10 million devices now running the Windows 10 OS in the country, Microsoft reports.

In practice, this will mean two changes that will happen automatically when Chinese users upgrade to Windows 10, with or without their consent. Under the contract, Baidu.com will now be the default homepage on Microsoft’s Edge browser, as well as its default search engine.

The partnership has been entered with the aim of providing world-class operating system technology and services to users in the country.

Today Microsoft announced it’s partnering with Chinese Internet giant Baidu.

“We remain deeply committed to delivering Bing around the world and we’re also committed to offering locally relevant experiences – like Bing in China”, said Windows VP Yusuf Mehdi. Baidu will also introduce standalone, universal apps for cloud, search, maps and video for Windows 10 soon.
