Microsoft has officially confirmed the golden version of Windows 7 SP1.

In a blog posting on Thursday, Microsoft’s Russian Windows Virtualization team confirmed that the final build of Windows 7 SP1 is 7601.17514.win7sp1_rtm.101119-1850. The Russian site also explains that the Service Pack will be available publicly today. Microsoft generally releases Service Packs on a Tuesday so it’s not clear whether the Russian technet post is referring to a public release to select partners or a full web release. WinRumors understand the software giant will ship the release to its OEM partners today but that a web release is expected at a later date.

The software giant posted a software update on Tuesday that applies to versions of Windows 7 and Windows Server 2008 R2. The update (KB976902) is a prerequisite necessary to successfully install and to remove any service packs to all versions of Windows 7 and Windows Server 2008 R2.

Microsoft fueled speculation of a January release of SP1 when it released a Service Pack Blocker Tool in November. The software maker typically releases Service Pack Blocker Tool Kits around two months before service packs are released. The software giant published a Release Candidate build of Windows 7 in October, marking its final push to RTM.

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.

Windows 7 recently celebrated its first birthday after selling over 240 million licenses in the first year of sales. Microsoft officials have previously promised that SP1 will be available by March 31, 2011.
