Changing Internet Explorer settings

The System Cleaner can remove temporary files and traces left by the Windows operating system. While these history traces can be helpful, they also reveal your activity to other people and can consume lots of disk space. To maintain your privacy and system performance, you can remove all these files and traces.

To change Internet Explorer settings:

  1. Open the main interface.

  2. Click System Tools, the System Cleaner tab, then the Cleanup Settings link.


    The System Cleaner Settings panel opens.


  3. On the left side of the panel, click Internet Explorer.

  4. On the right side, click in the checkboxes to select or deselect items. Items with a checkmark will be cleaned. When you're done, click the Save All button.

    The settings are described in the table below.

Internet Explorer cleanup options

Address bar history

Removes the list of recently visited websites, which is stored as part of Internet Explorer's AutoComplete feature. You see this list when you click the arrow on the right side of the Address drop-down list at the top of the Internet Explorer browser.


Deletes all cookies from your computer. Cookies are small files that store information about your interaction with a website and may reveal what sites you visited.

Be aware that if you remove all cookie files, some websites will not "remember" you. This means that you may need to re-enter passwords, shopping cart items, and other entries that these cookies stored.

Temporary Internet Files

Deletes copies of stored web pages that you visited recently. This cache improves performance by helping web pages open faster the next time you visit them, but also reveals your visited sites to other people using your computer and can consume a lot of space on your hard drive.

URL history

Deletes the list of recently visited websites. You see this list when you click History on the Internet Explorer toolbar. While this history can be helpful, it also reveals your visited sites to other people using your computer.

Setup Log

Deletes log files created when you update Internet Explorer. After you install the updates, you no longer need these files.

Microsoft Download Folder

Deletes the contents in the folder that stores files you last downloaded using Internet Explorer. After downloading, you no longer need these files.

MediaPlayer Bar History

Removes the list of audio and video files recently opened with the media player in Internet Explorer.  (The cleanup does not delete the files, just the Windows "memory" that you opened them or searched for them.)

Autocomplete form information

Deletes data that Internet Explorer stores when you enter information into fields on websites. This is part of Internet Explorer's AutoComplete feature, which predicts a word or phrase based on the characters you begin to type (for example, your email address or password).

Clean Index.dat (cleaned on reboot)

Marks files in the index.dat file for deletion, then clears those files after you reboot the system. The index.dat file is a growing Windows repository of web addresses, search queries, and recently opened files. This option works when you also select one or more of the following options: Cookies, Temporary Internet Files, or URL History.

Note: Index.dat functions like an active database. It is only cleaned after you reboot Windows.
