There's been talk floating around for quite some time about the coming of Windows 7 SP1. Today, we've got some details out of Redmond -- ''For Windows 7, SP1 includes only minor updates, among which are previous updates that are already delivered through Windows Update. SP1 for Windows 7 will, however, deliver an updated Remote Desktop client that takes advantage of RemoteFX introduced in the server-side with SP1 for Windows Server 2008 R2.
Windows 7 is ready for commercial deployments now and many industry experts have recommended that customers do not wait for SP1. Many organizations are already in the process of deploying and are receiving benefits from their Windows 7 deployment''.
The short version: Windows 7 SP1 will pretty much just be a rollup of updates that have been previously released.
The slightly longer version: there will be other 'minor' updates, including support for a kicked-up remote desktop client (using RemoteFX) and Dynamic Memory support. Both of those are Windows Server technologies, so they're not of much interest to anyone running Windows 7 at home.
SP1 does historically act as a 'green light' to system administrators that it's OK to upgrade to the new OS, but according to Brandon LeBlanc that hasn't been the case this time around. In his words, "Many organizations are already in the process of deploying and are receiving benefits from their Windows 7 deployment."
