Nearing the end its life cycle, Service Pack 1 for Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007 was retired yesterday. Upgrades must be made to Service Pack 2, which is a requirement for the August 2010 Cumulative Update.
Before downloading and installing the updates, Microsoft suggests downloading the white paper “Understanding Updates for SharePoint Products and Technologies,” which includes articles for deploying software updates for Windows SharePoint Services 3.0 and SharePoint Server 2007.
Installations of the Windows SharePoint Services 3.0 Language Pack and SharePoint Server 2007 Language Pack are optional. To aid with updating, deployment road maps are also available.
