Windows 8 public beta (also known officially as Windows 8 Consumer Preview) ISO file is now available to download, available in both 32-bit and 64-bit.
Windows 8 Consumer Preview Product Key: DNJXJ-7XBW8-2378T-X22TX-BKG7J
Download the .ISO file and then burn it into a DVD so you can install Windows 8 Consumer Preview from it. You can have an option to use a Virtual Machine to play around with it or to dual-boot your Windows system (I’m doing the later, replacing my Windows 8 Developer Preview).
I haven’t installed it yet (about to after this post) so I can’t give any comment on it. Feel free to drop a comment here to share your Windows 8 Consumer Preview impressions. Mine will come in a post some time later next week most probably.
