Taskbar buttons for Universal apps remain on the Windows taskbar when the app is moved to another monitor?

I realize this is on the Known Issues list for Windows 10 but it has gotten so annoying that I had to frustrating DisplayFusion.

Is this a low priority? It seems like core functionality.

It's not that it's a low priority, but so far it's been nearly impossible to fix. It is still planned for 9.0 as long as we can find some lucking in finding a way to remove Universal app buttons from the taskbar (they don't behave the same as regular Win32 apps, unfortunately).

That makes sense... thanks for the update.

I ended up following your instructions to hide the Windows taskbar and use DisplayFusion on all three monitors.

It is a good workaround to get the desired behavior.

Excellent, glad to hear you found a workaround for now

Can confirm it's still an issue; albeit low priority indeed.
The workaround does work for me as well; but feels a bit dirty if that makes sense.

Researching into UWP apps, it looks like injection is the ONLY answer.
And we can't expect DisplayFusion to automatically inject into UWP apps on load up, that would be insanity on several practical and security levels.
I did try NtQuerySystemInformation hook, but even after removal it persists.
So would have to find the correct function it uses to index what is visible to the taskbar..

Until Windows adds support for hiding "Foreground" apps, it cannot be done.
However I had an idea.
What if we hooked into the windows taskbar instead?
Surely it has a list of visible windows; which we could "remove".

Anyway, thanks for the workaround

@Barry: Thanks for the thoughts on this! I'm not sure on that stuff but I will pass your notes to our developers.
