I have a MOSS installation that I am trying to bring up from version 12.0.6679.5001 to 12.0.6690.5000, which as I understand is the highest possible version for SharePoint 2007 (I need to reach this version so I can restore a content backup from another farm).
According to Steve Chen's version tables for 2007, you need the MS14-22 security update to reach the final version. The problem is, I cannot figure out where to download this patch. I have run Windows Update on the SharePoint server and there are no Important or Optional updates left. If I click on the link to MS14-22, there is a description of the patch, but no download. The KB articles for WSS and MOSS seem to suggest that this patch is distributed through Windows Update and also provide no download link. How can I obtain this patch?
