Microsoft unveils Windows 8 for public test
Reuters Seattle : Microsoft Corp unveils the first widely available test version of Windows 8 on Wednesday, giving the public the first chance to try out the slick, new-look operating system it hopes will restore the company's fading tech supremacy. Windows 8, as the first Microsoft operating system compatible with low-power microprocessors designed by ARM Holdings Plc, will run on tablets as well as desktops and laptops. "The operating system has begun to be seen as largely irrelevant," said Sid Parakh, an analyst at fund firm McAdams Wright Ragen, which holds Microsoft shares.
