We had one new WSUS related Knowledge Base article published last week, this one regarding an issue where after upgrading to Windows Server Update Services 3.0 Service Pack 2 (WSUS 3.0 SP2) on Windows Small Business Server 2008, the configuration wizard defaults to the operating system language in the Choose Languages dialog instead of the languages previously selected by the administrator. If the user does not review the selections, this behavior might lead the languages being reset to the default selection.
If you think this may apply to you, you can check out all the details at the link below:
