Internet Explorer (No Add-ons)
Internet Explorer No Add-ons Mode provides an Internet Explorer process environment free of ActiveX controls, Browser Helper Objects and other third party code that could contribute to issues with the browser. Use this mode to determine if an issue is being caused by code loading in the Internet Explorer process.
If the issue not present when running in No Add-ons mode, you can use the Manage Add-ons interface to isolate the specific add-on components that are contributing to the issue.
To open Internet Explorer (No Add-ons), from the Windows Vista default Start menu, click All Programs, Accessories, System Tools, and then click Internet Explorer (No Add-ons).
