Using CC 2.09.6, on xp system. No matter what, url histories coming back.

So when you put in first letter in the url box. previous urls pop up.

Happens with latest IE and Firefox, on this particular system. All other temp files clear as expected.

Running on other xps' URL's clear first run.

Thank u in advance!

Try turning autocomplete off.
IE: Tools>Internet Options>Content>Autocomplete-settings.
Firefox Tools>Options>Privacy then the top three checkboxes. The autocomplete in Firefox is also related to "pages visited" history. So if you un-tick the second box but leave the history intact, autocomplete will remember the pages logged as having been visited. (Those can individually be deleted from the history.)
