Microsoft has launched it’s release preview version for Windows 8.
Windows 8 is expected to be stable for tablets which may compete with other tablet & mobile devices, iOS & Android.
Windows 8 is a new operating system by microsoft with a whole new concept.
It has nice metro UI & boots faster than previous version of windows.
Programmers who are interested in making applications for Windows 8 may download the release from http://windows.microsoft.com/en-US/windows-8/download
Since this is not the final version, I recommend running it in a virtual machine so that your host operating system is not affected.
