Another blog post by Jim Allchin on the Windows Vista Blog:

One of the interesting things about the release of a major version upgrade like Windows Vista is that there are so many new features, that it might take you a while to discover all of the deep capabilities built into the product. Some features you will discover are nice changes that improve specific uses. Others can dramatically alter the way you use computers and make you much more productive. In Windows Vista, one of the best examples of this is finding and organizing things. It really starts with the Start Menu where, instead of hunting for the program you want to run, you can type in a few letters of the program's name and see it appear right on the top of the Start Menu. But search on the Start Menu is about much more than finding programs -- it can also be used to find a document that you are looking for as well. For example, if I am looking for a document about my friend "John", all I need to do is type in the word "John" and I can see all of the documents with the word "John" in the document, title, or tag placed on the document. If you do this, you will also notice that the search is not limited to the file system -- in fact, contacts from Microsoft Outlook that might help me get a hold of John are also displayed. I can also click on the "show all results" button that appears right on the Start Menu to see a list of all of the content (such as documents, web pages, emails, and even music) that relates to the word "John."
