A window of opportunity opens

China's government banned Microsoft Corp's Windows 8 from State purchases. The move will create more business opportunities to domestically created operating systems, analysts said on Wednesday.

"The push for local operating systems is a golden chance for Chinese software companies to gain ground, but it also challenges their product and technology levels," said Zhang Yumu, vice-president of the online security company Beijing Rising Information Technology Co Ltd.

Microsoft described the decision as "extremely unexpected" on Tuesday.
