Registry location of Default Windows 10 apps.

Original Title: How to handle default apps in Windows 10 registry

Good afternoon,

I'm working on an installer, which is setting file associations in the Windows Registry: it sets the following keys:

HKEY_CLASSES_ROOT\<own_entry> (refers to a <caption>)

HKEY_CLASSES_ROOT\<caption>

HKEY_CLASSES_ROOT\<caption>\shell\open\command

HKEY_CLASSES_ROOT\<caption>\DefaultIcon

On previous Windows versions, this was sufficient for setting file associations.

Now on Windows 10, some new feature has been added: "Default apps", which can be found using "Start", "Settings", "System", "Default apps".

There seem to be some issues due to this new feature. In order to address those features, I'd like to know where in the registry the data of this "Default apps" is stored (it is stored in registry, I might hope?).

Best regards

Dominique
