Microsoft reveled the features for Windows 10 including the return of the start menu. The program will come equipped with a new web browser called Spartan. Windows 10 will also feature a voice activated search agent like Apple's "Siri."
The launch date has not yet been released but is expected to be later this year.
Windows 10 will be free for those using Windows 7 or Windows 8 for a limited time once it is released.
