SILVERLIGHT est disponible via Microsoft Update...
If you're really astute, you may notice that we released a very minor update to the Silverlight 1.0 plug-in this week. There's no changes to the core itself, apart from a fix to improve logging of Windows Media audio-only streams; as a result, machines won't auto-update unleIfss the site they visit explicitly requests the new version. (The new version is build 1.0.30109.0, incidentally.)
The main reason why this release is interesting is that we've made a few changes to the installation process to enable systems administrators to deploy Silverlight into enterprise environments more easily. Starting from today, Silverlight is available as an optional update for Windows XP and Windows Server 2003 via the Windows Server Update Services tool (and, inevitably, Microsoft Update , since WSUS relies on Microsoft Update as its source for updates).
