China has banned the Windows 8 operating system from being installed on any government computers, deepening problems for American technology companies in the country.
Reuters reported that China's Central Government Procurement Center issued the ban, effective immediately, as part of a notice on using energy-saving products.
"We were surprised to learn about the reference to Windows 8 in this notice," Microsoft said in a statement.

"Microsoft has been working proactively with the Central Government Procurement Center and other government agencies through the evaluation process to ensure that our products and services meet all government procurement requirements. We have been and will continue to provide Windows 7 to government customers."
The official Xinhua news agency cited Microsoft's recent decision to sunset support for the much-older operating system, Windows XP, as part of the decision.
