As we first published earlier today, the software giant is now letting everyone to have a taste of the latest version of Windows 8. Previously Microsoft said that the Release Preview was going to be available sometime during the first week of June, but it seems that because the Chinese version leak started showing up all around the Internet, the company decided to launch RP several days earlier.

Before proceeding with the ‘Release Preview’ installation, be sure to check two things: Make sure that you meet the minimum requirements — you’ll find all the details at the bottom of this page — and that you have selected the correct ISO image to download (e.g., language and version). Microsoft has created a “Windows 8 Release Preview Setup” that will help with these steps. The Setup will also give you a compatibility report and upgrade assistance.
