Windows 7 team blogs about the changes since beta for the RC on Desktop Experience, Networking, Control Panel, Windows Media Player, Device Stage, Sound UX, Windows Explorer and Libraries and Performance
I have Windows 7 Beta on a laptop and I getting use to it already! The gripes I had about the Taskbar is not a problem to me anymore. I am like it now! At Brighthub.com, I mention the dozen of new and enhanced or changed security features on Windows 7 Beta. For example: I don’t see “Software Explorer” any longer in Windows Defender (not sure if that is final move by MS), I tried the cool Bitlocker To Go, the cool image backup (but not on the article as I forget about it!).
