What is an ActiveX control?

ActiveX controls are small programs, sometimes called add-ons, that are used on the Internet. They can enhance your browsing experience by allowing animation or they can help with tasks such as installing security updates at Microsoft Update.

Some websites require you to install ActiveX controls to see the site or perform certain tasks on it. When you visit such a site, Windows Internet Explorer asks if you want to install the ActiveX control.
