Windows 7 has RTM’d if you didn’t know.
The final few minutes before RTM are a sign-off process where each and every team that contributed to Windows formally commits to having successfully executed the work necessary for the product to be in the release process. We gather one last time (for Windows 7) in the “Ship Room” and a representative from each team signs (literally) and signifies their team’s readiness for manufacturing. We thought we’d share this moment with you here today.
From the Engineering Windows 7 blog, check out the RTM signing off video below.
