Microsoft (MSFT) confirmed over the summer that its next-generation desktop and tablet operating system Windows 8 will launch on October 26th, and now the company is getting ready for its big day. Microsoft on Monday sent invitations to media for a Windows 8 launch event scheduled to take place in New York City on October 25th. No further details were provided. Microsoft’s new Windows 8 and Windows RT operating systems carry Windows Phone’s tile-based user interface over to desktops, laptops and tablets when they¬†launch next month. BGR took a look at Windows 8 back in February and called it the first step toward a terrific unified experience across all of Microsoft’s platforms.
