Windows 10 and setting a portable app as a default applciation

Hey guys,

I've been setting file types to portable applications from the platform, like setting all video types to Media Player Classic and this works well. I only had to select a video, click "open with" then choose MPC from the custom program button and set as default.

After that, I could easily go in the Windows settings and select MPC for every video type without having to set every single video file extension to MPC.

With InfranView however, it's a different story. Even after clicking "open with" on several image types and selecting InfranView as default, I still cannot select it in the Windows 10's default photo viewer application as the only option is "Paint".

No idea why MPC appeared automatically after setting the app as a default for a file, while it doesn't with InfranView.

I could set every extension manually, but there's a LOT:

Anybody found a way to add a portable application to the possible list of defaults?
