**After installing SBS 2011 I immediately wanted to install Windows 2008 R2 SP1 but instead I got offered 59 other updates and no SP1! So of course you can just roll with that and eventually after cycles of updates and reboots you’ll get SP1 offered …but I really wanted to lay down SP1 saving time and then build from there. Why isn’t it being offered though …even if you scan via Windows Updates? Google didn’t give me any good results on Windows 2008 R2; however, remembering that since the Vista ‘major release’ kernel unification change to align the desktop and server kernel led me to look at Windows 7 information.
The following article identifies three required updates that must be installed in order to get offered W2k8R2 SP1. Interestingly I was offered the KB2534366 patch (required a reboot) via WSUS but I had to go out to Windows Update to be offered the KB2533552 patch (didn’t require a reboot). KB2454826 is the latest patch to be added to this list as this KB article has gone through multiple revisions over the years.
