Windows Server 2008 R2 and Windows 7 SP1 has shipped. Here’s the bottom line:
The Windows Server team has information on SP1 here: http://blogs.technet.com/b/windowsserver/archive/2011/02/09/windows-server-2008-r2-and-windows-7-sp1-releases-to-manufacturing-today.aspx
Technical information on the service pack can be found here: http://technet.microsoft.com/en-us/library/ff817622(WS.10).aspx
Feel free to use the comments as an informal place for questions/feedback if you like. I will have some followup information on the service pack a little later.
What is the approximate time it should take to install this on a very fast system?
What took it so long after the final build was completed in November to release it to web *this month*?
Very fast is realitive <G>. Standalone installations on my machine are right around 30mins or so, about the same as any other service pack.
As for the second question, that's not something I can answer because I dont know. My guess would just be the fact that the test cycle hit over two major holidays probably added to the time it took to get it out the door.
testing and writing the documentation about the Sp1, creating of other hotfixes, updating the KB pages for the old KB articles ....
