Unlike Windows search "Everything" initially displays every file and folder on your computer (hence the name "Everything").

Everything could be that replacement you're looking for. This simple, fast tool indexes absolutely all the contents on your hard drive (hence its name) and puts them into an ever-growing database that you can search with keywords, like you use any regular search engine.
