Gabe Newell called this platform's store a threat to Steam, and it was announced at Computex 2011. Gadgets were removed from this platform, and this product is the first of its kind to implement universal searching from anywhere within an application, true inter-program multitasking, and a built-in file system explorer. USB 3.0 is natively supported on this platform, as is 3D Printing. This platform allows its users to see a graph of file transfer speed, and clicking a monitor's corner in this operating system allows users to switch between apps and activate a "Charms" bar. For 10 points, name this operating system whose Start screen features live tiles, recently created by Microsoft.
