Windows 2008 r2 sp1 installation not moving after 40 % This is an issue to pursue in the Windows Server 2008 R2 forum(s). Once the service pack installation STARTS --- WSUS is no longer part of the process.Lawrence Garvin, M.S., MCITP:EA, MCDBA, MCSA Principal/CTO, Onsite Technology Solutions, Houston, Texas Microsoft MVP - Software Distribution (2005-2011) My MVP Profile: http://mvp.support.microsoft.com/profile/Lawrence.Garvin My Blog: http://onsitechsolutions.spaces.live.com

I'm seeing the same issue, did you get it resolved?

Has the system update readiness tool been run without error? http://www.microsoft.com/download/en/details.aspx?id=14668 Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows]

For me, I had to uncheck IE9, and make sure SP1 was the only thing being installed. I also used Microsoft Update, instead of the standalone SP1 installed. That fixed the issue for me.
