Windows 7 SP1 Release Candidate (RC) build 7601.17105.100929-1730 has leaked publicly ahead of a scheduled release at Microsoft’s Professional Developers Conference next week.
The build, leaked by Ivan Zukonov/WZOR, weighs in at 353MB and is currently circulating peer-to-peer file sharing and bittorent sites. GeekSmack notes that both x86 and x64 variants are available.
SP1 will include RemoteFX which provides rich 3-D graphical experience for remote users. The service pack also will include a series of incremental updates, previously released on Windows Update for both Windows 7 SP1 and Windows Server 2008 R2 SP1.
RemoteFX is a new enhancement to RDP’s graphical remoting capabilities. The idea behind RemoteFX is to allow for a full remote experiences including multiple displays, Aero and multimedia streaming to all types of client devices including low cost thin clients. RemoteFX achieves this by using a technique known as host-based rendering. This technique allows for the final screen image to be rendered locally on the remote PC after being compressed and sent down to that remote host. The enhancements are expected to greatly improve video streaming across remote sessions which is currently one of the major drawbacks of virtualized computing.
Microsoft is planning to release Windows 7 SP1 RC at next week’s PDC 2010 which kicks off on October 28 at the Microsoft Campus. Windows 7 recently celebrated its first birthday after selling over 240 million licenses in the first year of sales. A final version of Windows 7 SP1 is expected early 2011.
