Today, in a couple of hours from now, you will be able to download Windows 8 Consumer Preview officially and directly from Microsoft. The company will release Windows 8ย Consumer Preview during an event that will be held at Mobile World Congress (MWC) in Barcelona byย 3PM and 5PM (CET). You will be able to download the preview fromย ย msdn.microsoft.comย and install it on yourย 32- or 64-bit x86 machine. No version for ARM will beย available. Theย Consumer Preview is like a beta, so replacing yourย currentย OS with this preview is not a good idea.ย It is recommendedย that you install it on a separate computer or create a different partition just for Windows 8 Preview to avoid conflicts between data. The best to do isย visualizeย it using programs like Virtual Box,VMware Player, or Parallelsย (for Mac).
To install the beta, the computer isย primarilyย requiredย to at least haveย 1GHz processor(x86, or x64), 1GB of RAM, 16GB hard drive. And since Windows 8 is a touch-based OS, it works best on multi-touch monitors or laptop; so if you want to play around with Windows 8 touch input, you better waste some cash on a multi-touch laptop or monitor.
Update:
You can finally download it atย windows.microsoft.com
