The actual operating system is like the Windows 7 of Windows 8, since Windows 8 got a bed reputation. Although, this operating system will be a big step forward. Microsoft added the old Windows 7 Start Menu back, and their personal assistant "Cortana" is integrated to it. Metro apps will now be able to be opened up in a window, just like any old desktop programs. A new browser code-named Project "Sparta" with Cortana integrated is also in progress, which will replace Internet Explorer. Xbox games will also be able to be played trough Windows. In terms of Windows Phone, a version of Windows 10 will be available for it. And best of all, Windows 10 will be a free upgrade for Windows 7, 8, and 8.1 users for the first year after its release.
