CleanCache 2.0 is a free (for 1 - 2 systems), very powerful Internet Explorer 6.0 and Windows XP cleaner. It will delete all IE tracks (including cleaning/deleting index.dat files), AutoComplete, WinXP tracks and the deletion of user created additives. The following is a comprehensive list:

Temporary Internet Files and index.dat
Internet Explorer History and index.dat
Internet Explorer Cookies (with selective save) and index.dat
Typed URLs (with selective save)
Internet Explorer Form AutoComplete (using either CleanCache 2.0 built in AutoComplete deletion or by using IE's built in function)
Recent Documents
Start Run History
Search History
Windows Temporary Directory
Windows Media Player
Windows Word Pad
Clipboard
Registry MRUs
Recycle Bins
Create additives to delete user specified files/directories and registry entries

I wrote CleanCache 2.0 to be very unobtrusive...just set it and forget it. CleanCache 2.0 runs from the system tray and will clean after Internet Explorer browser close, Windows startup and Windows Shutdown.

Requires .NET Framework 1.1
