Searching on MSDN directly from the IE Address Bar
Here's a little trick I've been using for quite some time. This registry file will create a SearchUrl entry named "msdn" in your registry (it really could be named whatever you want). This SearchUrl will then allow you to search for a topic on MSDN directly from your browser's address bar without you having to go to the MSDN web site first. So you then can type something like: "msdn System.Net.NetworkInformation" directly on your address bar and IE will look it and display the results. It might work with other search engines/sites too (Yahoo, Google, etc.), just change the url of the page and place "%s" where the parameter to be searched will usually be placed on the site's url and you're done.
In my case I have setup two separate entries: "msdn" and "msdn-es" (for the Spanish version of MSDN)
