    - OK, that confirms there are at least two different mechanisms for some people (not all) experiencing a change of association
    1. Some people have old version desktop apps installed- unrelated to the associations that change
    2. A change of association triggered by an update.

    Your (minimal) case makes it hard to imagine what might be the trigger.
    I'm wondering if there's any clue in the Event Log.
    Spent plenty of time going through the event log to see what if anything caused the issue with .pdf files. So far I have found nothing.

    Thanks for this link much appreciated.

    The article also talks about another strange issue that I have noticed. The "Open with issue", which also does not list other apps, just the default ones.

    In some cases the option "open with" is not even available when right clicking on a file type.

    My news item's been moved although this is likely to be recurring and important issue, so I won't bother posting there again.

    See this, referring to KB3135173,
    Windows 10 Forced Update Resets Default Apps To Microsoft Products - Slashdot

    Updategate: Microsoft 'aware' of problem causing app defaults to reset- The Inquirer

    - from which came the suggested registry modification.

    However, it would be better (I think) to uninstall the update, and hide it (see the Tutorial section) as in the article quoted by Seoras (above)

    Hmm, open with not available sometimes...

    (Just for amusement (?), count how many posts this MS guy wrote before getting the point.. then threw the kitchen sink at it..

    Default File Type Associations - Restore in Windows 10 - Windows 10 Forums

    Each reg file therein includes 'Open With' so I suggest you pick an extension for which you have no 'Open With', merge the relevant reg file from the above, see if you have 'Open With' (might need to at least log off/on).
