Windows 10: "Always use this app to open .xml files" not working

Every time when I receive an .xml file in Outlook and try to open it, it will prompt a dialog and ask me to choose an APP to open it. Even though I tick "Always use this app to open .xml files", the next time I open it, same thing happens. So can anyone help me fix it. Many people are affected by this issue.

Problem when opening a XML file

Hi Roberto - From another source I received a suggestion to open the offending file in Wordpad and to save it as an Office Open XML document which would have an extension of '.xml.doc' then remove the '.doc' part

That idea unfortunately hasn't worked for me. Having saved the file as suggested I then tried to open it. In Internet Explorer and MS Edge I get a completely blank page. In Notepad, Wordpad or Office XML Handler (which uses Notepad) I just get unintelligible
"mumbo jumbo". In XML Notepad it states "Data at the root level is invalid Line 1 Position 1 and asks if I wish to open it using Notepad. Answering yes just results in "mumbo jumbo" as before.

The file only opens correctly in Word 2016, (i.e. showing all the elements etc.) but if I try to open any of the other XML files using Word, I get a message that "The file contains custom XML elements that are no longer supported in Word. Saving the fie will
remove these elements permanently", and only the data for each element is shown for these files and there is no sign of the various elements themselves.

Don't know if any of the above gives some indication of what is wrong, but it's all very frustrating . Can't help feeling that it is something very simple! I would stress that the other four xml files used by the program all open properly in a Edge window

 

I can not open the xml files with the xml editor

When I double click on a .xml file an error message is appearing that there is no appropriate program to open this kind of files. I tried to match the xml editor program with the files having a .xml extension and this didn't work too.

Please tell me a way to pair the xml file editor with the .xml extension files.

 

Windows 10 - how to open an XML file by default USING the correct M/S program (XLS, DOC or PPT)?

This is not <quite> the answer, but solved an issue very similar. On a new W10 I needed to set the default app for .xml files to IE. All suggestions using settings did not allow me to specify IE. The only way I found to do this was to locate (any) .xml
file then 'open with'. Then 'Choose another app'. Then scroll to the bottom of the list and select 'another app'. Finally IE appeared in the list and I could set IE as the default. Obviously this should apply to most other apps.
