Some who have tested Windows 8 complain about the change from earlier versions of Windows, which could force users to relearn how to operate their computers, the New York Times reported Sunday.
Sinofsky acknowledged the difference with older versions but said Windows 8 was designed for the “modern world”.
“It’s a completely different feel. It’s clean. It’s beautiful. It’s intuitive,” he said.
Sinofsky said Microsoft hoped to add up to a billion new customers with Windows 8, which aims to replace earlier versions of its dominant operating system.
“It’s (Windows) used by over a billion people around the world and with Widows 8 we’re aiming towards the next billion,” he said.
Microsoft has been hurt by piracy in China. Industry group the Business Software Alliance last estimated in 2008 that 80 percent of software used in China was pirated.
Ralph Haupter, Microsoft’s chairman and chief executive officer for the Greater China Region, said the mainland was an important market.
“China is a big business opportunity for us. China is also the place where many devices get developed, designed, built, but these days, even more importantly, get sold,” he told reporters.
A company spokesman said Microsoft does not release sales and revenue figures for China alone.
