The final preview version of Windows 8 has been made available for download, so if you want to get a peek at what the final version will feel like, you can download the Release Preview and give it a test drive.
Unlike the Release Candidate stage seen with past Windows versions, this won't be exactly the same as the final version. We already know that Microsoft is ditching Aero for a new Metro-styled interface, and that this interface won't appear in the Release Preview.
However, if you've been playing with Windows 8 and want something a bit more stable than the current Consumer Preview, this is where the party is. To install it, just download the EXE from the link below to create a bootable flash drive or CD. You can also just grab an ISO image here.
While you can upgrade your system to the Windows 8 Consumer Preview, only upgrading from Windows 7 will be treated as a full upgrade. If you don't want to overwrite your Windows 7 installation, you can always dual-boot them side by side or install it in a virtual machine instead. Check out Microsoft's blog post on the subject for more details. To see everything that's new in Windows 8, check out our first look and in-depth tour.
