Back at PDC 2004 Microsoft announced Longhorn which eventually became Vista. Those who attended PDC in 2004 got an early build of Vista to play with. Microsoft will continue the tradition and will give an early build of Windows 7 at PDC 2008. As of today you can find screenshots of Windows 7 build 6519. There are also many sites dedicated to Windows 7 rapidly taking shape on the web. I have put together this list of links which you can visit to get some information on Windows 7. I wish I was going to PDC to see all the action around Windows 7. But not going to PDC is not stopping me to read everything there is to read about Windows 7. Here are some links I have visited:
