As a public service announcement, I'd like to point everyone to
http://www.copernic.com ... these guys rock. There are two pieces of software there everyone should try. Copernic Desktop Search is similar to products from MSN and Google that index your harddrive. However, Copernic has several features and a user interface that make it my top pick. Copernic Tracker (if you have $50 to spare) is a great tool for tracking web pages. (Especially handy for me since I no longer waste time checking on my multiple webcomics and friends' livejournals. I simply do my thing and the program tells me whenever a webpage changes.)
