I found this link on Neowin.net about the new Windows Desktop Search technologies coming out of Microsoft. Apparently Microsoft has released a beta or “preview” of their new search technology v4.0 for Vista, Server, and XP. You can find the links to download via the link below. I’ve just installed the Vista SP1 version right now for testing. It’s supposed to fix a ton of bugs and make searching very fast.

NOTE: This is a preview release and as such may have some minor bugs. Also, to install for Vista you have to have SP1 installed.
