Good news to all Windows 8 lovers, Microsoft today officially released Windows 8 Release Preview and it is now available for download in 14 languages. This is final pre-release, and includes Windows 8, Internet Explorer 10, new Windows 8 apps for connecting to Hotmail, SkyDrive,Messenger and hundreds of new and updated apps in the Windows Store.
The Windows 8 Release Preview marks the final phase of development before releasing to manufacturing (RTM) and this mean , this build is the final version of Windows 8.
Before you download and install the Windows 8 Release Preview: it is important to note that like the Windows 8 Consumer Preview, it is pre-release software. If you are comfortable running preview software on your PC and ok with doing a few technical tasks (like formatting a hard drive) here and there, then you’ll probably do just fine with the Windows 8 Release Preview.
If you are on the Windows 8 Consumer Preview, please make sure you read the Windows 8 Release Preview FAQ for important information on moving to the Windows 8 Release Preview. As always, before moving to a pre-release operating system, make sure you back up your files. The best way to give feedback is to take part in the Windows 8 Release Preview forum.
The build number is 8400 and is sized at 2.5GB for 32bit and 3.3GB for 64-bit. It is available for download via ISO or web installer, much like the Consumer Preview.
