WinRumors exclusively revealed earlier on Wednesday that the software giant is planning to release Windows 7 SP1 on February 22. Microsoft has now confirmed it has Released to Manufacturing the first Service Pack for Windows 7. “Today we officially handed off the final release (RTM) of Windows 7 and Windows Server 2008 R2 Service Pack 1 (SP1) to our OEM partners” said Microsoft blogger Brandon LeBlanc in a statement on Wednesday. LeBlanc also confirmed the build number in a blog comment on Thursday. “@Cosmin, the full build number is 7601.17514.101119-1850. ” said LeBlanc. MSDN and TechNet customers will receive the bits on February 16, followed by a general web release (RTW) on February 22. Copies of Microsoft’s Windows 7 SP1 RTM update leaked last month to file sharing websites. As always, we’d advise against installing leaked bits on production machines but at this time Microsoft has confirmed 7601.17514.101119-1850 is the final 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.
