Following up on last week’s entry, WSUS 3.0 SP1 will be available today, Tuesday, March 25 to WSUS, Windows Update site and Catalog site. The Service Pack will gradually be released through the Automatic Update pipeline starting about 14 days after this date to WSUS servers or machines just running the WSUS 3.0 Administration Console connected directly to WU/MU via AU. It should be noted that Vista’s Windows Update Control Panel Applet or WUA may allow you to install the update earlier. This can be done within WUA via the first screen and elect to download and install pre-selected updates.
