A new pre-release Build of Windows 7 Service Pack 1 has made its way out of Redmond and into the wild, as the service pack is advancing toward the first Beta development milestone. Windows 7 SP1 Build 7601.16556 has been leaked and is now available for download through various illegal third-party sources, including BitTorrent trackers. Microsoft has yet to confirm that Windows 7 SP1 reached a specific development milestone, release deadlines for Beta, RC and RTM Builds, or detail the evolution that the upgrade will bring to the table.
In mid-March 2010, the Redmond company did indicate that Windows 7 SP1
would be nothing more than a standard service-pack release, and a minor upgrade in this sense, and confirmed two new features impacting the virtualization stack, Microsoft RemoteFX and Dynamic Memory
. As it was the case with Vista and Windows Server 2008 SP2, Service Pack 1 will be designed not only for Windows 7, but also for Windows Server 2008 R2. In this regard, the new RemoteFX and Dynamic Memory features will benefit Windows Server 2008 R2 SP1 customers the most.
