While Microsoft Windows 8 setup assistant utility provides and excellent way to download and create operating-system bootable installation media (CD/DVD/USB/ISO), it does not provide any means to use an existing .ISO file for creation of these bootable media options.

To create an bootable CD, DVD or USB setup disk from an previously downloaded and saved Windows 8 ISO file follow the steps demonstrated below.

Microsoft Windows 8 M1 Build 6.1.7850 got leaked for public downloading but if you don't want to mess-up with a pre-build version of the future OS and still want to see what's in here is a video demonstration of "Windows 8 Build 7955". The video shows the new logon process and the metro design language.

Finally, we have a leaked public download of "Windows 8 M1 Build 6.1.7850" - scheduled for release in 2012 the next major update to "Windows OS" will support system-on-a-chip (SoC) and mobile ARM processors. The very first public leak of the successor to "Windows 7 operating-system" has the following attributes :

Microsoft Windows 7 is due retail release on October 22, 2009 and according to some reports Microsoft has already started working on Windows 8, we have seen artists conceptualizing Microsoft Windows 8 GUI and features via creations like Windows 8 Transformation Pack and Windows 8 Superbar but the real shocker came when I saw a leaked version of Microsoft Windows 8 Professional Edition available for download on a torrent portal accompanied with the following screen-shots.

Don't be surprised as there is no publicly available Windows 8 GUI concept yet, but similar to previously shared Windows 7 Theme artists have now started to create Windows 8 theme concepts which in my opinion does not look very different then current Windows 7 interface, this Vista transformation pack concept consists of Theme, Logon Screen, System Tray icon, Tclock Lite and Wallpapers.
