Apps :: Disable How To Want To Open This File

On every computer I've installed Windows 10 on (a dozen+) despite me setting all my default file types and applications, the first time a specific file type in opened, it still asks if I want to use this program. I've attached a picture of the first time I'm trying to open a MOV file.

Like I said, I've already specified that it should open with VLC, but it still asks anyways. I've tried this through Settings and Control Panel but it still doesn't work.

In the picture it does say iTunes is a new application, which I know would probably make this happen, but even without a new application being installed after setting my default file types, it still happens. Once I get through this screen it won't ever come up for MOV files again, but it will if I opened an MP4, and nearly any other file type on the computer. It doesn't usually happen with anything besides media files, but ANY picture; movie or audio file will do this (among several random others). This happens on EVERY Windows 10 I install, and I'm tired of having to keep two dozen dummy files and opening them all to disable this message on each computer. Is their a way I can prevent this message from coming up.
