NEW YORK ( TheStreet) -- Microsoft ( MSFT) has confirmed that its eagerly-anticipated Windows 8 operating system will be generally available in October, marking a significant milestone for the tech giant.

Critics, however, have warned that Windows 8 will not be able to halt Apple's ( APPL) growing popularity with consumers. Key Windows 8 features include a new user interface with touchscreen capabilities, Xbox Live integration and more efficient power usage. A version of Windows 8 called Windows RT will support chips designed by ARM ( ARMH). Do you think Windows 8 will be a winner?
