Neowin is reporting the leak of Build 7100 which is the RC version of Windows 7:
Redmond still haven't called that plumber, the official RC build has leaked online at the usual places.
We revealed yesterday that the Windows 7 RC build was 7100 and according to many Neowin members the x86 version has leaked just a short time ago.
We expect the RC will be available to the public shortly and Redmond could still hit the rumored May 5th date. There is speculation the software giant will hold off until May 15th, the last day of Tech-Ed 2009.
