Hi
I use Agent Ransack, and I have for years.
It's really, really fast, finds everything, and is easy to use.
Once installed all your have to do is, right click on the location you want to search, select Agent Ransack from the menu, and type in what you are looking for.
Agent Ransack - Free File Searching Utility
Give it a try, you won't believe how well it works compared to Windows search engine, and it's free.
Example, I had it search from my root drive of C:\ for a specific file, total time to search the whole drive, with all the sub folders, it found 3 copies of the file in 5 seconds.
