Microsoft has selected testers to help with scenarios on a Service Pack 1 update for Microsoft Update. The beta is only expected to last until the end of January. Microsoft released the Update service last year after extensive testing that brought together Windows and Office Updates on one page. End users have the option to use Windows Update or the new Microsoft Update service.

No new features will be added to the service, the purpose of the beta is to test fixes that have been made since the release last July.
