Certain files always show Open With dialog regardless of default program set

[genosmrpg7899]

My default program for MP3s is WMP9, but regardless of what default program I have set, the dialog always opens when I try opening an MP3 from the explorer.

I have voidtools Everything installed which is the only place I haven't seen it do this and immediately opens the default program that is set.

Can you uninstall OpenWithEx and verify that this behaviour does not occur with the vanilla Immersive Open With UI?

I have noticed the same with images. I have a default image viewer set for most common types (qView), but sometimes I have less common images for which Win10 Photos is still the default (e.g. PNG). Immersive Open With does not open for these images, e.g. it's not trying to suggest "You have new programs that can open this filetype", but now with OpenWithEx installed, I've noticed a few times when I open an image, it displays the Open With window.

Seems it still occurs with the immersive UI. Not sure atp.

I can only confirm this bug.

I tried to set Windows Mail as e-mail client for Firefox (when you click on an e-mail link on a webpage) and it would always pop up again (openwithex) even though I set it to always open with that application.

After uninstalling Openwithex it worked flawlessly (with the Win10 openwith dialog)

It would be highly appreciated if the dev could fix that. I can only assume that it might have to do with Microsofts aggressive way of protecting default apps.

In my case I realized it with images files too (*.jpg).

Yep, you have to turn of UCPD.sys driver to resolve it.
The dev should make it a standard routine in installer. The software simply wont work without that. UCPD is somewhat aggressive and make autonom decisions sometime. Microsoft hide this entry from services.msc, you have to disable it with command console.

I can't find any UCPD.sys driver on my system and I have this issue. I'm on Windows 8.1 if that matters.

OpenWithEx is only meant for Windows 10+. Also I'm pretty sure the UCPD.sys driver doesn't exist in Windows 8.1 beause it's something Microsoft added in Windows 10.

An important follow up @genosmrpg7899 @Darthagnon: does setting the default handler for the file type in OpenWithEx fix things for that specific file type? If not, it's probably an OpenWithEx bug.

I think you may otherwise be seeing standard Windows functionality.
