Microsoft announced today that it will launch the next version of it’s operating system Windows 10 on July 29th. That mid-summer date represents aggressive timing for a company that has at times had problematic launches for it’s major products. Over the past few months Microsoft has been releasing increasingly polished preview builds of the software and now appears comfortable going to market with it.

Windows 10 will be available as a free upgrade for users of Windows 7 and Windows 8.1. To publicize that, Microsoft is adding a small notification in users task bars which began showing up last night. Clicking on the taskbar notification, pops up a slide show extolling the benefits of Windows 10. Some of the new features include: the return of the Start menu, an all-new Internet browser, and Cortana, a digital personal assistant making to Google Now or Apple’s Siri.

To kick off the launch date announcement Microsoft has released a new video highlighting Windows 10 main features.
