It was only a matter of time until someone posted a copy of a beta release build of Windows 7 Service Pack 1 publicly. The release is then spread via P2P services with no option to control or block the release from being downloaded.
The leaked Windows 7 SP1 release has the build number 7601.16562.100603-1800. It was originally distributed to select beta testers but has since then founds its way to P2P sites and other distribution services.
A word of caution for users who think about downloading this beta SP1 release. Malicious users often use releases of popular applications to spread their malware with those releases.
But there is another reason why users should wait with the downloading and installing: Windows 7 SP1 will not add any new features to the operating system. It is rumored that Service Pack 1 might include USB 3.0 support and enhanced Bluetooth and Wi-Fi stacks but that has not been confirmed by Microsoft yet.
The beta release will expire between April – July 2011. It is not clear yet if it will be possible to update from a beta Service Pack to the final release.
A public beta of Windows 7 SP1 is expected to be released in July
