Fix Unwanted Changes to Settings in IE8

If the home page or other settings have changed, you can reset all browser settings except for Favorites, Feed, Internet Connection Settings, Group Policy Settings, and Content Advisor Settings by following these steps:

• Close all windows except for one Internet Explorer window.
• Click Tools and then click Internet Options.
• In the Internet Options dialog box, click the Advanced tab.
• Click Reset.
• In the warning box that appears, click Reset.
• Click Close and then click OK twice. Restart Internet Explorer.

To prevent unwanted changes in the future, ensure that you have all Microsoft Security Updates installed and are using anti-malware software, such as Microsoft Forefront or Windows Defender.
