The new software represents a reset and rebirth of the bets that Microsoft made with its Windows 8 operating system.
Windows 8.1 contains a grip of new features, including new built-in applications, fresh user-interface changes, and a more powerful search technology that elevates Bing as a component of the Microsoft services suite. SkyDrive also has a prominent place in Windows 8.1, as Microsoft works to ensure that it continues to manage its users’ files wherever they are stored. (For a quick look at why that matters, head here.)
4am PDT is 6am EST (our time).
But this is a staged roll out so not everyone will see it to upgrade at the same time.
