Microsoft on Tuesday announced Windows Blue will be officially called Windows 8.1. Furthermore, the new version will arrive as a free Windows 8 update via the Windows Store. The news was revealed at the JP Morgan Technology, Media & Telecom Conference in Boston, by Tami Reller, Chief Marketing Officer and Chief Financial Officer of Windows. Microsoft also noted there are more than 70,000 apps in the Windows Store, a noteworthy number but still a far cry from Android, iOS, and even Windows Phone. On the Blogging Windows blog, Brandon LeBlanc, Microsoft’s Communications Manager for Windows, detailed where the company is coming from with its Windows 8.1 vision: “During her remarks today, Tami reiterated our goal of delivering continual updates to create a richer experience for Windows customers. Windows 8.1 is part of that and continues the journey we first began with Windows 8 last fall.”
