New Windows 7 Screenshots and Information

There is still much talk going on about the Windows 7 Milestone 1 release which dates a few days back. While most blogs on the Internet are still arguing about the validity of the screenshots and videos a Russian user has posted tons of additional screenshots of new and old aspects of the Windows 7 Milestone 1 release.
Reiker posted an extensive review of several of the new features that Microsoft did add to this release of Windows 7. To be honest, a normal user would probably think he would be sitting in front of Windows Vista and not Windows 7 if someone would make the test. The two operating systems look really alike and most differences are rather cosmetic in nature.
Still, there are some functions that have been implemented in Windows 7 that are not available in Windows Vista or previous operating systems.
A so called HomeGroup is created during setup which seems to be a mandatory step. The HomeGroup lets the user share files with other computers in the homezone. My guess is that Microsoft tries to improve on the networking aspect of the operating system by distinguishing between Work and HomeGroups.
