A UK Microsoft manager has been corrected by the company for saying the design of Windows 7 was borrowed from Mac OS X.
The company's partner group manager Simon Aldous told the PCR website that Microsoft had tried to "create a Mac look and feel".
He added, "We've tried to listen to what customers want in terms of a much slicker user interface and the ability to engage with it far more intuitively.

"One of the things that people say an awful lot about the Apple Mac is that the OS is fantastic, that it is very graphical and easy to use. What we've tried to do with Windows 7 - whether it's traditional format or in a touch format - is create a Mac look and feel in terms of graphics."
Microsoft refuted the claims with a post from Brandon Le Blanc on the company's official blog.
He said, "I hate to say this about one of our own, but his comments were inaccurate and uninformed."
The post read, "An inaccurate quote has been floating around the internet today about the design origins of Windows 7 and whether its look and feel was "borrowed" from Mac OS X. Unfortunately, this came from a Microsoft employee who was not involved in any aspect of designing Windows 7."
