This article describes the Microsoft Silverlight 5 for Windows download version 5.1.40620.0.

Original product version: Silverlight
Original KB number: 3075609

There was a time when Adobe Flash was the king of the internet, and Microsoft wanted a piece of the pie. In a bid to make a breakthrough, the company came up with a tool known as Silverlight,.

1. Microsoft Silverlight will reach the end of support on October 12, 2021. Even though Silverlight is still supported by Microsoft, active development was stopped several years ago. Right now, Silverlight is only supported on Internet Explorer 11. Silverlight enabled developers to build both desktop and web applications.
2. Microsoft Silverlight is a component in many web browsers that helps them stream and display video, music, clickable menus, and other types of 'rich media' content.
3. In approximately 15 months from now, Silverlight will effectively cease to exist. On October 12, 2021, users will no longer be able to download the IE plugin needed to use applications created with it.

The Silverlight 5 for Windows download version 5.1.40620.0 is available.
