Microsoft shipped a big update to Windows 8.1 earlier this year with improvements to the mouse and keyboard experience, but the second upcoming update is minor in comparison. Available on August 12th, the second update, which Microsoft is not calling Windows 8.1 Update 2, will include precision touchpad improvements, a change to enable PCs to act as a Miracast receiver, and a reduction in login prompts for SharePoint online. Back in April when Microsoft originally showed off the new Start Menu, the company was planning to make it available with Windows 8.1 Update 2 in August. Those plans changed, and it appears Microsoft is now holding back most of its radical changes for the Windows 9 release next spring.
