WSUS group is changing from "Office Commucations Server" to "Office Communications Server and Office Communicator"

This category will contain updates to components offered for various components of Microsoft Office Communications Server 2007, Microsoft Office Communications Server 2007 R2 and Microsoft Office Communicator.

I'm glad to see this, because official Office Communicator updates have been traditionally a little tricky to track. Currently, I'm recommending Office Communicator v2.0.6362.76 for current and future installs of OCS 2007 R1, which can be found here.

From the WSUS blog:

Office Communications Server 2007 and R2 manages all real-time communications including: instant messaging, VoIP, audio and video conferencing. Microsoft Office Communications Server 2007 and R2 also powers presence, a key benefit of Microsoft unified communications that unites the contact and identity information stored in Active Directory with the ways people communicate. Security updates can be released through this category periodically.

Office Communicator is a unified communications client that helps people be more productive by enabling them to communicate easily with others in different locations or time zones using a range of different communication options, including instant messaging (IM), voice, and video. Integration with programs across the 2007 Microsoft Office system — including Word, Excel, PowerPoint, OneNote, Groove, and SharePoint Server — gives information workers many different ways to communicate with each other via a consistent and simple user experience.
