Back in January 2010, when we announced the possibility of Windows 7 SP1 being released soon, many people were surprised. Few days later we got hold of the leaked screenshots which proved that the information is not a rumor. And mid-last month, a leaked version of Windows 7 SP1 made rounds on blogosphere and the torrent sites. Now again, a new version of Windows 7 Service Pack 1 has been leaked on the torrent websites carrying the Build 7601.16556.

Blogsdna reports that

Wzor the prime source of multiple Windows 7 Build leaks also continues to leak Windows 7 Service Pack 1. Now it’s Windows 7 SP1 Build 7601.16556.100421-1510 v.172 leaked by Wzor.


Similar to the previous leaked version, all we can see are bug fixes and nothing new. Here are hashes of Windows 7 Build 7601.16556.100421-1510 SP1.
