The release of the first Service Pack for Windows 7 in an inevitability. Microsoft has already spoken publicly about Windows 7 SP1, stating that it will be coming but it won't be packed full of changes that can't already be had from Windows Update.
Now the first real glimpse of SP1 is here as an early version of the software package has leaked into the internet's various P2P avenues. The build string of the leaked version is "6.1.7601.16537.amd64fre.win7.100327-0053" which indicates that it's a build from March 27.
GeekSmack has acquired a copy and grabbed a number of screenshots and reported that installation is drastically faster than the install process for any of the Service Packs for Windows Vista.
Of course, we don't recommend anyone to download Windows-critical software that doesn't come from Microsoft. Find it and try it at your own risk, and never on a primary-use computer.
