You read that right; you can search for stuff in your Command Prompt, which surprised the heck out of me, too.
Here’s what you do:
Open a Command Prompt by going to Start and then typing in “cmd” minus quotes in your search bar. You should see something like this at the top:

Press Enter and your Command Prompt should open up.
Now say you’re looking for a specific file somewhere in your file tree. Just Right-Click anywhere on the Command Prompt screen and select “Find…”. Type in what you’re looking for and whoomp, there it is!

Somebody at Microsoft must still have love for the Command Prompt!
