I didn't know Windows 8 was released.
The final RTM (Release to Manufacturing) version is not out yet, but the Windows 8 Release Preview is available now for anyone to download and try out: http://windows.microsoft.com/en-US/wind ... se-preview
Window 8 RTM is scheduled to be released on October 26.
I have to warn you though - it's very different from previous versions of Windows, and a lot of people have given it negative reviews. I still think it's too early to tell at this point in time though.
