What’s new in Windows 10 build 10122

Important change: “With Windows 10, all apps – both Classic Windows apps and Universal Windows apps – will be unable to invoke a prompt to change your defaults, only Windows.”
I wonder how this will play out for installers that change default file associations, or applications that try to “take over” certain file types?
