Recent leaks have unveiled Microsoft’s plan to give Windows a serious improvement over predecessors. Currently, Windows can update itself to fix bugs or security holes, but maybe in the future Windows will be able to easily upgrade the operating system too. Currently, in internal builds of Windows 9, this functionality is available. When the technical preview is released to customers, this ability to upgrade the build from Windows Update may or may not be present. Nevertheless, Microsoft may build this functionality into the final release of the operating system. Giving customers a simple and reliable way to upgrade their OS without reformatting and reinstalling their system would be a well received feature.
