Making Silverlight Easier for Systems Administrators to Install...

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 unless the site they visit explicitly requests the new version. (The new version is build 1.0.30109.0, incidentally.)

image 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).

Many customers have requested help with deploying Silverlight internally, and this change will hopefully be welcomed by enterprises who want to distribute Silverlight within their organizations using their established management tools. By adding it as an optional update, enterprises can control the roll-out of Silverlight within their organizations and schedule its installation as a background task so that the perceptible impact is minimal, and ensure that end-users can view Silverlight content without requiring administrative rights to install the plug-in.

I'm really glad this is now available: the need for administrator rights to install a web plug-in is not unique to Silverlight, of course, but it's been raised a number of times as a potential blocker to enterprise adoption. Having this available will solve that problem and make it far easier for enterprise administrators to control deployment of Silverlight to their users.
