Rumors are flying about Microsoft planning to offer Windows 9 at no cost if you are currently running Windows 8.1 with all other updates installed. Windows 9 will support ultra-high-definition (UHD) TVs and 3D mode, will include capabilities to backup and restore the system image to the cloud. The final version of Windows 9 is expected to be released in the spring of 2015. Microsoft does not want to get stuck in another Windows XP situation with enterprise hanging onto Windows 7, so the idea of a free upgrade may do the trick.”]
