In Pictures: Leaked features in Windows 8.1 Update...
Available through Windows Update
According to a leaked report, unlike the Windows 8.1 upgrade, which was released as a free download for Windows 8 users but only through the Windows Store, Update 1 will be pushed through the standard Windows Update tool. This will probably (and hopefully) work out more conveniently, as the Windows 8.1 upgrade process tends to be inconvenient due to the quirky nature of the Windows Store UI and what has appeared to be its servers’ difficulty in delivering the download quickly.
