Enable Quick Search In Folders

Windows Vista has a new feature that lets you quickly search in a folder by just starting to type, which will focus the search box. This comes in handy when searching a large folder. To enable this feature, open any folder and click the 'Organize' button then select 'Folder and Search options'. Next, click on the 'View' tab and scroll to the Advanced Settings box. Select the 'Automatically type into the Search Box' option then click 'OK'.

You can now simply type into the Search box and Windows will show all the related files associated with your search.
