Microsoft Windows President Steven Sinofsky has shown off the Windows 8, a touch-screen version of the operating system that works on tablet devices.

Sinofsky said that Windows 8 uses "tiles," and not icons for navigation between applications.

The new OS was displayed on a 10.6-inch touch-screen tablet, Bloomberg reported. Microsoft claimed that the OS can also work on desktop computers.

"What we set out to do with Windows 8 was really try to reimagine what we could do with a PC," Sinofsky said.

"You could sort of say we coloured outside the lines."

The company also displayed the OS at the Computex show in Taipei.

Microsoft vice-president Julie Larson-Green said the new OS Windows 8 is the company’s biggest OS change since Windows 95.
