Everything:

Everything is a search engine for Windows that replaces the normal
Windows search with a much faster one. Unlike Windows search,
Everything initially displays every file and folder on your computer.
You can type in a search filter to limit what files and folders are
displayed. Everything only uses file and folder names and generally
takes a few seconds to build its database. 1,000,000 files will take
about 1 minute.

Version 1.1.4.301 adds -search command line option, improved status of servers under the tool menu, and other fixes.
