How to find a web page history?

How can I find all the pages some one visited other than through the history? Meaning the history only keeps the last 20 days. But beyond that is there any place the computer keeps all the web pages some one visited?

I think the HKeyCurrent User only keeps track of the typed URLs. But the urls through google search or other searches are not there.

If the browser doesn't store it, it doesn't get saved. Not unless there was some other software running on the machine tracking it. Or the computer accesses the internet through a proxy that is setup to log all internet usage.
