Custom handler for the "print" event of the context menu of specific files?

Question

Seal

Good afternoon.

What are the ways to register a custom "print" event handler for the context menu of some extensions on modern systems ? Interested in Win2k8, Win2012, win2016, win 7/10.

I tried the old-fashioned way, to get into the
HKCR\.ext\verb\command\@default registry
- for some reason the path to the program does not work out. (tried on 10ke) The last time I did such nonsense on XP, it worked right away.

I googled the HKCR\SystemFileAssotiations\... section, but when I try to change
HKCR\SystemFileAssotiations\.ext\shell\print\command\@default - the path to the program
, nothing happens either.

I tried to google something specific, how to code such a software, but I did not find a fresh example without MFC.
(you can C++, .NET)

Maybe there is a ready-made software where you can simply select an extension, specify a command (including the standard one - verb in terms of M $) and the path to the program - the "make beautiful" button?

PS: the question is a sub-question of this .

UPD: M$ found a section in the docks https://docs.microsoft.com/ru-ru/windows/win32/she...
But the devil will break his leg there...

UPD2: it looks like here is a tutorial https://www. codeproject.com/Articles/174369/How-to...
But the question is the same, is there really no way without a bicycle?

I can’t speak for everything directly, but in most cases, for .ext, the default value is the type name associated with the program (for example, I now have PDF24.Reader for PDF). And in HKCR there is a separate branch with this name, in which there is already a Shell subfolder, Print in it, and Command in it with a default value in the form of a launch string. I suppose it's worth trying this way, and not producing folders directly in HKCR \ .ext
