Here is a quick way to ensure all temporary internet files are automatically deleted in Internet Explorer on exit :
1. Select the gears icon and then Internet Options in IE 9.
2. Go to Advanced > Security section.
3. Enable the option â€œ Empty Temporary Internet Files folder when browser is closedâ€.
Close the browser and re-launch it.
So once the above setting is enabled, all the accumulated temporary internet files in IE for the session will be deleted once the browser is closed.
this doesn’t work at ALL. every time I close my browser, and check for Temp. Internet Files with CCleaner, I see anywhere from 100MB to 400 MB in Temp. Internet Files.
