Microsoft plans to hold a launch event for its upcoming client operating system, Windows 8, on October 25, 2012. The event will be held in New York. In all likelihood, the event leads up to a midnight launch of the operating system on the 26th. Microsoft's next big launch for the year, the Surface, could be part of the event. Windows 8 is Microsoft's next major update to its flagship product, which radically changes its user-interface for the "post-PC era." It is also the first mainline Windows version since Windows 95 to support a machine architecture apart from x86 and IA-64 (Windows 8 RT, supporting ARM).
