setting the Default Apps doesn't work anymore on Windows 10

Since around a week ago, setting the Default Apps doesn't work anymore. Here's what I do:

MS Windows Explorer -> Click Right-Mouse button on a file (e.g. abc.txt) -> Open with -> Choose another app -> Select "Notepad++" and Check "Always use this app to open *.txt".

After I do the above steps, the default app does NOT change from Notepad to Notepad++.

I tried the following, but they did not work.

  1. changing the Windows account from local account to MS account.

  2. Settings -> Default Apps -> Choose default applications by file type -> Select ".txt" -> Choose "Notepad++"

Thanks for your effort and time to help...

Solution

  • On a Windows 10 Pro (Version 1803, Build 17134.345) following worked for me:

    • Open Notepad++ as an administrator
    • Menu > Settings to open the "Preferences" dialog
    • Click "File Association"
    • Click "Notepad"
    • Click ".txt".
    • Click "->" to register notepad++ as the program to edit .txt files
    • Click "Close"

    As a second step do the same you described in your question.
