Just for clarification, you will probably read/hear the terms GA and RTM from time to time. They stand for General Availability and Release to Manufacturing:
General Availability: 22 October 2009
Release to Manufacturing: End of July
According to Brandon LeBlanc they will complete work on Windows 7 RTM in late July.
Brandon LeBlanc (May 11):
If the telemetry we receive from the Windows 7 RC meets our expectations in terms of quality, then we expect to hit RTM in 3 months or so
So, do you think it is a possibility that Microsoft is already working on SP1 (Service Pack 1)?
I think many people would want Microsoft to focus solely on RTM and not on SP1, but it is indeed a possibility that they already work on SP1.
I’m sure you’ve already seen it, but did you know that they changed the leaked picture of SP1 after it had been released? Pretty curious.
