Windows 8.1 is now the official name for Microsoft's next major update to the Windows product family, which has been referred to as "Windows Blue" over the past couple of months. The first public preview of the operating system will be unveiled on June 26. Microsoft also announced that Windows 8.1 will be a free update for users of Windows 8.
Speaking at the JP Morgan Technology, Media & Telecom Conference in Boston, Windows product manager Tami Reller outlined her company's plans with Windows 8.1. The first public preview of the operating system will be held on the sidelines of the Build developer conference in San Francisco, and the operating system will begin rolling out later this year. To Windows 8 users, it will be available as a simple update package through Windows Store.
