Windows 7 is complete. After previews and beta versions and then the Windows 7 Release Candidate, the Windows 7 team has decided that Windows 7 is ready to release. Windows 7 is making its way onto MSDN and TechNet, and is already with PC makers.
Windows Technical Beta Program members will be getting their free Windows 7 in the next few days.
This isn't the exact version of Windows 7 that you'll get on a new PC, because there are still content deals for Media Center to lock down and it doesn't have the Windows 7 web browser ballot screen that users in Europe are likely to see when they set up a Windows 7 PC (new or upgraded).
