Windows 8 computers to go on sale in October

Computers running on the next version of Microsoft's Windows operating system will go on sale in October.

Most industry analysts expected Windows 8 would go on sale in the fall to ensure that the machines running on the operating system would be available for the holiday shopping season. Consumers and businesses who don't want to buy new computers will be able to buy Windows 8 and upgrade their systems.

New versions of Windows typically come out every three years, but this update is the most widely anticipated overhaul of the software since 1995.

Applications will appear in a mosaic of tiles on Windows 8. Microsoft also designed the operating system so it can run on personal computers or touch-based tablet computers.

As part of its efforts to develop more touch-based software, Microsoft also announced the acquisition of Perceptive Pixel Inc. The deal gives Microsoft access to technology used in large multi-touch displays for TV broadcasters, as well as government, defense, engineering and educational markets, Microsoft said.

Terms of the Perceptive Pixel purchase weren't disclosed.

Windows 8 is being counted on to help revive demand for laptops and other personal computers.

The operating system's versatility is expected to encourage leading PC makers such as Hewlett-Packard Co. and Dell Inc. to release hybrid machines that are part laptop, part tablet computer. Both HP and Dell have also indicated they plan to release tablet computers powered by Windows 8, thrusting them into competition with Microsoft's Surface.

Microsoft is releasing Windows 8 computer manufacturers during the first week of August.
