I want to know the answer to the following question:
When did the Chinese government ban the purchase of Windows 8 products?
All the background I'm provided with is that "The Xinhua News Agency claimed that Windows 8 was being banned in protest of Microsoft's support lifecycle policy and the end of support for Windows XP (which, as of January 2014, had a market share of 49% in China), as the government "obviously cannot ignore the risks of running OS [sic] without guaranteed technical support."". Is that enough to answer the question?
Answer: no
