Wzor is once again reporting that the Windows 7 winmain_win7rc branch has reached 7079.
Yesterday build 7077 leaked via BitTorrent and we speculated this could be the build that would be "renamed" to 7100 for the RC. It appears that isn't the case and Microsoft has built 7078.0.090406-1758 and 7079.0.090407-1902 over the last few days.
We still expect Microsoft to name the RC build shortly and all bets are on 7100. Last month Microsoft hinted at a May public release for the RC.
