It sure didn’t take long for Wzor to get the recently released private beta of Windows 7 SP1 out in the public. The latest leak – from Russia, with Love – packs both Windows 7 Service Pack 1 beta and Windows Server 2008 R2 Service Pack 1 beta into one package for you to download.

The leaked build 7601.16562.100603-1800 is the same which was released to testers two days ago (though there is no guarantee that it wasn’t tampered with). here are the build details from Wzor.

According to Wzor, the Windows 7 SP1 Beta download ISO contains three different packages based on platforms. There is the Windows 7 SP1 Beta for x86, Windows 7 SP1 and Windows Server 2008 R2 SP1 for x64, and Windows Server 2008 R2 SP1 for iA-64.

The official Windows 7 SP1 beta would be released for public download towards the end of July, until then if you want to trust a potentially modified build, then that’s your call. And remember, Google is your best friend.
