Brandon LeBlanc over at the Windows Team Blog has just confirmed that Microsoft has “handed off the final release (RTM) of Windows 7 and Windows Server 2008 R2 Service Pack 1″ to their OEM partners. The first service pack for Windows 7 and Windows Server 2008 R2 will be available on February 16 for MSDN and TechNet subscribers, and on February 22 for all customers via the Microsoft Download Center or directly via Windows Update.
For Windows 7, SP1 will help keep your PCs well supported by delivering ongoing updates, many of which have been made previously available through Windows Update.
Brandon confirmed that the final build number is indeed 7601.17514.101119-1850. Most users should however wait with the installation of the service pack until it becomes officially available, considering that it does not contain a lot of new features or new patches for the Windows 7 operating system.
