Where are the default program settings stored?

    Question

  • Where are the settings stored in Windows 10 for default programs. They seem to be read only in our windows 10 testing, because if someone were to change their default from IE to Chrome, at boot, it changes back to IE.

  • Hi daweberchisago,

    How did you configure the default program?
    For Windows 10, we could configure the default program settings here. The way how Windows 10 handled the default programs has been changed. We`d better to configure the default programs here.
    Settings\System\Default apps

    There are several registry keys for default program.
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\ (for current user)
    HKEY_LOCAL_MACHINE\SOFTWARE\Classes(default setting for all the users)

    If you want to force the default program settings, we could try the following gpo.
    Administrative Templates\Windows Components\File Explorer\Set a default associations configuration file
    The template could be exported with command line "Dism /Online /Export-DefaultAppAssociations:\\Server\Share\AppAssoc.xml"

    Best regards

    Sounds like something is protecting the registry.  Try booting in safe mode to see if your changes stick there.  Test in safe mode and then come back to a normal boot.  Then chances are whatever is protecting will still be there but this time preserving your real preference.

    This is a well-known issue, very broadly discussed over quite some time, and third-party software vendors have made a big stink about it to MSFT.

    MSFT changed the way that Win10 checks/protects against 'hijacking' of default progs, and software has to be changed to use the new 'not hijacking' approaches, or Win10 will override/revert it back.


    Don [doesn't work for MSFT, and they're probably glad about that ;]
