I myself don't have it installed on my machine. NO problems at all. I haven't found any sites/videos etc.

Fundamentally, Silverlight is Microsoft's competitive answer to Adobe's Flash, the long-standing dominant standard for multimedia Web applications. Silverlight integrates animations, video, and interactivity (the ability to click on an animated item and trigger a response). I have been exploring the possibilities of Microsoft Silverlight and how it runs in web browsers. I just wonder if Silverlight requires the.NET framework? Meaning that Mac or Linux users cannot run Silverlight. I will be making the application using the.NET framework 3.5.

That I couldn't view without it. I do think I've heard. That Netflix (maybe) needs it, but as I don't use Netflix I can't vouch for that. My bottom line is. No you don't need it. (MY opinion)Yes Netflix uses it, you can't view Netflix without it. From my understanding, for the general user, it is mostly used in different video streaming services.

So I don't think it's necessary to have unless you stream a lot of video's on certain sites, I think ABC and sites like that use it to stream their videos at times. The thing is, you don't necessarily need it, but it's also not hurting you to have it, sure it takes up space, but it's not slowing you down, and if you don't use it, you'll never know it's there, so I would say just keep it there and maybe sometime in the future you might use it, if not, no harm done.
