Support for Internet Explorer ended on June 15, 2022
Internet Explorer 11 has been permanently disabled through a Microsoft Edge update on certain versions of Windows 10.If any site you visit needs Internet Explorer 11, you can reload it with Internet Explorer mode in Microsoft Edge. We recommend you use Microsoft Edge for a faster, more secure and more modern web browsing experience.
Add-ons are apps that InternetExplorer uses to interact with web content like videos and games. Toolbars and extensions are also types of add-ons. Some common add-ons are Adobe Flash, Quicktime, and Silverlight.
InternetExplorer is designed to provide an add-on free experience, and will play HTML5 and many Adobe Flash videos without needing to install a separate add-on.
You'll only be able to install and use add-ons in InternetExplorer for the desktop. If you're trying to view a page that requires add-ons, view it in the desktop: swipe up from the bottom of the screen (or right-click) to bring up the app commands, select the Page toolsbutton 
Note:In Windows RT, add-ons aren't supported by either InternetExplorer or InternetExplorer for the desktop.
Installing and using add-ons
If you're missing an add-on that you need to view a page, InternetExplorer will let you know, and will prompt you to install the add-on. Some add-ons come pre-installed by other apps or your PC's manufacturer.

Turning off and removing add-ons
Add-ons can sometimes cause browsers to run slowly and crash, or they might pose a security or compatibility risk. You can turn off specific add-ons to help increase your browsing speed, or if you suspect they're causing problems for InternetExplorer. You can also remove add-ons that you're no longer using from your PC. It's a good idea to delete add-ons if you suspect they're causing performance, compatibility, or security problems.

The risks of installing add-ons
While add-ons can make your browsing experience better by giving you access to great web content, some add-ons can pose security, privacy, or performance risks. Make sure any add-ons you install are from a trusted source.
Enhanced Protected Mode and add-ons
Enhanced Protected Mode helps protect your PC and personal data from malware and other attacks. When it's turned on, add-ons such as toolbars, extensions, and browser helper objects can only run if they're compatible with Enhanced Protected Mode. You'll be notified if an add-on is incompatible. If you need to run an incompatible add-on, you can turn off Enhanced Protected Mode in the desktop browser.
Note:Enhanced Protected Mode helps protect your PC from malware and other attacks. Only turn it off if you're sure about increasing the level of risk to your PC.

-
Open InternetExplorer, select the Tools button, and then select Internet Options.
-
On the Advanced tab, under Security, select (or clear) the Enable Enhanced Protected Mode check box, and then select OK. You'll need to restart your PC before this setting takes effect.
