Although search in Windows 7 is pretty good, it’s geared towards finding documents. So if you’re searching for a program file or a library file (.dll) or some other non-document file, it’s not much help. Windows Search also searches file contents as well as filenames, which is useful but slow. To find any file fast, try Everything.
One of less than obvious tools Windows offers is the right-click menu within file dialog boxes. Give it a try: open an application and then press Ctrl-O or click the Open icon to display the Open dialog box. Right-click any of the files or folders displayed in that dialog and you’ll see a context menu pop open.
