The first service pack for Windows 7 (and Windows Server 2008 R2) is now less than two weeks away. Microsoft has announced on the official Windows Blog that the final, release-to-manufacturing build of the service pack has already gone out to PC makers. SP1 will become available to MSDN and TechNet subscribers on February 16, followed by a public release via Windows Update on February 22.
Now, keep in mind this isn't a particularly exciting service pack. The Microsoft blog post doesn't bother to hype it up, saying it will "help keep your PCs well supported by delivering ongoing updates, many of which have been made previously available through Windows Update." RemoteFX and Dynamic Memory support are also included for users running Win7 in a virtual machine under Windows Server 2008 R2.
There is one little nugget of new goodness for folks with Sandy Bridge processors, however: support for Intel's Advanced Vector Extensions, the new instruction set extension that promises quicker media and graphics processing. Third-party applications will have to implement support, too, but the foundation will be there.
