Thomas Deml on the IIS team posted a very cool Log Parser Gadget http://blogs.iis.net/thomad/archive/2006/10/30/IIS7-Logparser-Gadget.aspx

You can use this to execute a Log Parser query and display results in vista. This allows for some very interesting possibilites! Log Parser is one heck of a utility that will read the local file system, registry, event viewer logs, IIS log files, and more using a SQL style query language that has far more capability that you would imagine. Output forms include XML, text, SQL databases, screen, graphs, end more. See http://www.logparser.com/ for details and http://www.logparser.com/Resources.htm for even more details.
