I just upgraded from Windows 7 to Windows 10, and now, every time I open a file type I haven't yet opened in Windows 10, I get this dialog:
I understand that I can check the "Always use this app to open these files" box to get Windows to shut up about that particular file type, but with literally thousands of file types on my system and hundreds of programs governing them, I'll be doing this for years and years to come. How can I get Windows 10 to shut up and just let me keep using my existing file associations?
