Microsoft announced the release of Windows 7 SP1 and Server 2008 R2 service pack 1 today. This update as all Microsoft service pack updates contains the cumulative updates for Windows 7 and Server 2008 R2 previously released prior to the SP1 release. Microsoft has announced enhancements and fixes related to HDMI devices as well as printing enhancements. This service pack also introduces the RemoteFX technology that Microsoft has touted to enhance and improve the remote desktop experience with Server 2008 R2 as well as HyperV virtual desktops.
It appears that this release of SP1 is a minor one compared to service pack releases in the past and does not provide any major new functionality to Windows 7 or Server 2008 R2. The service pack can be downloaded from the Download Center here or via Windows Update.
Also of note for system administrators is that the Windows Automated Installation Kit for Windows 7 SP1 supplement was released today as well allowing system administrators to customize Windows 7 SP1 images. The new WAIK SP1 can be downloaded here.
