The October cumulative Update packages (former known as “Uber package”, now called “Full Server” package) are now available.

Download and installation instruction:

• Install SP2 for WSS and MOSS and also the Service Packs for the Language Packs as applicable or not done so far.
• Install the full server package for KB 974989 - WSS v3 (Oct. CU 2009) 
• Install the full server package for KB 974988 - MOSS (Oct. CU 2009)

Important notes about the cumulative update package

• The hotfixes are now multilingual. Therefore, there is only one cumulative hotfix package for all languages.
• One cumulative hotfix package includes all the server component packages. The cumulative update package updates only those components that are installed on the system.
• The cumulative packages are based on the last Service pack prior published.
  It is not recommended to install the packages on an earlier Service pack as the latest provided.

Note!

It is always recommended to test first the updates in a test environment before applying it to productive systems! Otherwise ensure that you have a full, valid backup of your farm/servers!
