As of today Microsoft has released the consumer preview of Windows 8.
There are several downloads for Windows 8 available at this time. Here’s an overview of the different kinds.
Windows 8 “Workstation” (All kinds of languages available)
Windows 8 Server Virtual Hard Disk (pre-installed)
Have fun downloading and remember if you have the Developer preview installed you cannot upgrade. You have to do a clean install.
Also this version doesn’t require a license key but will expire as of March 2013.
