The new Edge browser no longer supports Silverlight (as well as Flash, and some Java stuff) in order to be more secure. Most other browsers (Chrome, Firefox, etc.) are going (or have gone) in this direction because of the security and behavior vulnerabilities that can exist in these add-ons.

Windows 10 still includes the original Internet Explorer 11, but it is not anywhere that is easy to find. The shortcuts to IE 11 on your desktop, start, and taskbar need to be recreated; and IE needs to be set as your default browser so that it (rather than Edge) runs when you click a link.

Luckily, Windows 10 makes it very easy to find stuff. Search (Click on the magnifying glass on the bottom left, next to the start button), and type “internet” – right-click on Internet Explorer and “Pin to Start”, then “Pin to Taskbar”, and lastly, left-click it and choose “Open file location” – you will see the shortcut to IE – right-click that, and choose “Send to” and choose “Desktop (create shortcut)”. This process will put the original IE everywhere you need it to be.

In order to make IE open as the default internet browser (instead of Edge) when you click on links, search again for “internet” and click on the “Internet Options”. Go to the “Programs” tab, and click on the link to “Make Internet Explorer the default browser”. In the “Set Default Programs” window that has opened, find and select “Internet Explorer” on the left side, then click “Set the program as default” near the bottom right of the window. The next time you click on a web link or type a web address in the search bar, it should cause IE to open instead of Edge.

Now, one more thing: Other browsers (Chrome, Firefox, etc.) may realize that you have changed the default browser to IE, and may prompt you to change that (to set them as the default); this is entirely up to you, but if you wish to keep IE as the default browser, you may need to answer “No” to the other browsers (and check the box to never ask again).
