Have you installed the new beta MSN Toolbar with desktop search? Oh this is so cool. I do not want to go back to living without it.
Jay's blog over at MSN Spaces has a great write up. And
Channel9 has some videos ofthe development team talking about it and demoing features.
Get it from http://beta.toolbar.msn.com/Oh and they learned from some of the mistakes other desktop search engines have made and they don't indext the IE cache. Plus they index a lot more types of files than the other desktop search engines. For me I am sure glad that I can include OneNote files for example. And of course all my email is now indexed. And I have a lot of old email. :-)
Oh it does take a while to do the initial index but it is worth it.
