How to Create Multiple Associations for One File Extension

For simple associations (just "open" I guess), you may...

(a) Highlight any file of that particular type
(b) Hold Shift & R-Clk it, to get "Open with...." again.
(c) Check the "Always open with..." box at botttom.
(d) Select the proper app from the window.

However, if you still don't know what to associate it with... To
disassociate it...

"START button, Settings, Folder Options, File Types tab".

Use the D-Arrow to slowly scroll the list, all the while looking for
that file type to appear at "Extension:". At long last, while it is
highlighted, click "Remove". If the extension is, for instance, ".xyz"
you may first quickly scroll the list & look for "XYZ File". Remove that
one.

But make no guesses. If you cannot remember what that file type
(extension) was, post back. Terhune will put you under hypnosis with a
mile-long dissertation--- & shock your memory!
