Quicktime Reference Movies on Windows PC?

Now that Quicktime is not a good idea on Windows, how do you handle a reference movie created by Quicktime Pro? I created a couple for my website years ago but the reference movie (which is of file type .MOV) can't be played with Windows 10 built-in Quicktime support. Is there an alternative to just forgetting about such movies?

PS: FYI, here is some info from a read-me created by Quicktime that explains a bit about reference movies for web sites.

In the same folder as this instructional HTML file, QuickTime Pro has placed various versions of your movie optimized for web-delivery. Also in that folder is a reference movie, which selects the best version for your users' various devices and connection speeds.
