MRU Blaster does indeed delete the majority of MRU data. Interesting product. That said... It misses an important list... the autocomplete keys in IE. These keys are separate from the IE history and the MRU. They contain many pages of a site, not just the usual typed/searched/history lists. These keys can be even more revealing than history or typed MRU as they map any site you visit. You may type in www.cnn.com but the AC list often contains every page you visited at CNN. The AC list appears to be very deep. The rub is preservation of needed AC keys... Example... I need AC and saved password registry keys to work when I use Infopop forums like www.fiero.nl. Not having these keys function propperly would suck big time.
