Explanation:
Reset Internet Explorer settings
By resetting Internet Explorer settings, you return Internet Explorer to the state it was in when it was first installed on your computer. This is useful for troubleshooting problems that might be caused by settings that were changed after installation. When you delete personal settings, some webpages that rely on previously stored cookies, form data, passwords, or previously installed browser add-ons might not work correctly. Resetting Internet Explorer to its default settings does not delete your favorites, feeds, Web Slices, and a few other personalized settings. See the table below for a complete list of all settings and information about whether they are reset or maintained.

Resetting Internet Explorer’s settings is not reversible. After a reset, all previous settings are lost and cannot be recovered. Rather than resetting everything, you might want to reset specific settings or delete your webpage history. For more information, see the links at the bottom of this topic.
