Just got this in the mail:
As you know, Microsoft® Windows 7 was Released to Manufacturing (RTM) this afternoon, July 22, 2009. We are excited to be releasing what we consider our best OS to date and we couldn’t have done it without you, our Technical Beta Testers!
With the announcement of RTM, the beta program is officially closed.
Time to get ready and move my customers to Windows 7
