The installation for Windows 7 latest build 7077, fixes some minor bugs. I had the chance to play with the new Media Center and it offers a slick interface and easy navigation. . During this install, which only took 30 minutes, I chose the Business Network settings vs. Home Group, and it immediately found all my network PC's. This was problematic under the Home Group settings. Overall very fast, excellent compatablity, and a good ride. It still feels like Vista version 2. But that is not always a bad thing...Notice the addition of the Quick Launch Toolbar.
