SUMMARY

This article describes the Install On Demand and the "Automatically check for Internet Explorer updates" features in Internet Explorer.

MORE INFORMATION

Install On Demand

The Install On Demand feature specifies whether to automatically download and install Web components that can be installed by Internet Explorer Active Setup by using the component's cabinet information file (CIF) for Setup instructions. Typically, a Web page may need to download items to display the page properly, or to perform a particular task. For example, if you open a Web page that requires Japanese-text display support (Charset=euc-jp), Internet Explorer automatically prompts you to download the Japanese Language Pack component if it is not already installed and the Install On Demand feature is enabled.

For information about the types of components that can be installed by the Install On Demand feature, please visit the following Microsoft Web site:

NOTE: In Internet Explorer 6, components that can be installed by Active Setup by using the CIF for Setup instructions are controlled by the Enable Install on Demand (Internet Explorer) setting. Components that can be installed by using self-installing program files that are registered with Internet Explorer 6 are controlled by the Enable Install on Demand (Other) setting. For Internet Explorer 6 for Windows 2000, only Microsoft Windows Media Player 7 can be installed on demand if the Enable Install On Demand (Other) option is enabled. Install On Demand is not available for other components in Internet Explorer 6 for Windows 2000, and Install On Demand is not available for any components in Internet Explorer 5.x for Windows 2000.

For Internet Explorer 6 for Windows XP, no components are installed based on the Enable Install On Demand (Other) option. This option should not appear in the Advanced dialog box in Windows XP.

Automatically Check for Internet Explorer Updates

The "Automatically check for Internet Explorer updates" feature specifies whether to check the Internet to see if a newer version of Internet Explorer is available. With this option enabled, Internet Explorer checks the Internet for a newer version approximately every 30 days. If a newer version is available, you are prompted to download it. This feature is not available in Windows 2000. This feature is also not available in Windows XP.

Disabling These Features

The Install On Demand (Other) or Install on Demand (Internet Explorer) and Automatically check for Internet Explorer updates options are turned on by default in all versions of Windows except Windows 2000 and Windows XP. These features are not available in Windows 2000 or Windows XP, but these options are present on the Advanced tab in the Internet Options dialog box in Windows 2000 and Windows XP.
