A few days ago, Bryant from AeroXperience had made a blog post on his thoughts for what Windows 7 Milestone 3 has. Looks like he opened Pandora’s Box as since then, there has been a lot more information out about the build and it’s features, specially the Ribbon UI spreading through out bundled applications such as Paint and Wordpad. He mentioned the end of Sidebar as we know it, a trend which was obvious from the M1 build screenshots.
