The PC industry worldwide sold 136 million desktop PCs last year, along with 160 million traditional notebooks driven by keyboards and touchpads. Those big numbers explain why Microsoft is feverishly improving the desktop experience for "the next iteration of Windows."
At the Build Developer Conference earlier this year, Microsoft officially announced plans to return the Start menu to “the next iteration of Windows,” along with a new option to run Metro/Modern-style apps in their own windows on the Windows desktop.
Microsoft Executive Vice President Terry Myerson made the announcement at the Build Day 1 keynote on April 2, 2014. You can watch the clip on YouTube below, with Myerson's remarks coming a little more than two hours in to the morning’s proceedings.
