Get everything: https://www.voidtools.com/ (the alpha version can also index the content of files). It's search is instant. As in < 1 second for any file on any of your harddisks (even ones not connected right now).
For base linux cmdline tools I just install Git for Windows it includes tail, sed, grep, tee, iconv, less, scp and tons more. I need git anyways so win-win.
