Following the recently leaked Build 7601.16537 and Build 7601.16543 of Windows 7 Service Pack 1, a new build has now leaked to the wild. The leaked build is 7601.16556.100421-1510 Service Pack 1, v.172 and was compiled on 21st April 2010. Source of this leak is WZOR, who has managed to slip this one through Microsoft’s fortress yet again.

I have managed to get some screenshots from Windows 7 Ultimate – with build string 7022.winmain.090115-1850. This new leaked build has got some minor changes which are illustrated from the screenshots below.
