Windows 10: How to change default app on opening attachments in Mailbird

I use mailbird for my emails and have had no problem until now opening attachments. Today however, I have tried to open an attachment and it has tried in windows media which obviously will not work as it is a pdf file. I must have changed something without realising and now would like to know how to change the default app for opening my attachments. Help!

How to change default app for file type

'Open With > Choose another app' has three step, in the first it only offers apps registered for that file type. If you click 'More apps' it lists all registered apps regardless of suitability. Both these steps have the tick-box for 'Always use...' in my 18363.752. The third step, if needed, is 'Look for another app on this PC'. The 'Always use...' must be ticked before taking this step if you want the change to stick. However, WMP appears at the second step.

For a quick look at a JPG almost anything (including WMP) is more practical than Photos which on my system takes more than ten seconds just to open a photo. The OP is probably not aware that the Windows Photo Viewer is still available in W10, but hidden away. That's my default viewer for JPG.


Restore Windows Photo Viewer in Windows 10

And, once enabled, is available in Settings > Apps > Default apps.

 

How to change default app to open certain file types.

It's not as simple as it seems
Although it's easy as pie to change default apps by type file, but how to do it if I want to use app that's not on the default Window list?
Like in this example,



File is opened by IE but I have installed in my system programme called Notepad++ and I want it to open .xml files whenever i double click on them. But Notepad++ is not on the Windows list



So how to set this up to open .xml files with Notepad++?

 

Mailbird still shows in the show notification from these apps

Original Title[Mailbird]

Windows 10: settings: in 'notifications and options', 'show notifications from these apps', 'Mailbird' is listed; with all the buttons to turn turn on and off notifications etc. I uninstalled mailbird' a year ago. Why is it still there? Why can't I get rid
of it?
