For more information, see the section on Changes to how Windows 10 handles default apps in this post. When a user sets program defaults using Default Programs , the default setting applies only to that user and not to other users who might use the same computer.
Default Programs provides a set of APIs deprecated in Windows 8 that enable independent software vendors ISVs to include their programs or applications in the defaults system. Default Programs is primarily designed for applications that use standard file types such as. Applications that use their own proprietary protocols and file associations do not typically use the Default Programs functionality.
After you register an application for Default Programs functionality, the following options and functionality are available by using the API set:. Default Programs also provides a UI that enables you to register an application in order to provide additional information to the user. For example, a digitally signed application can include a URL to the manufacturer's home page. This restriction is a security feature that prevents a process from acting as an administrator without the administrator's knowledge.
Installation of a program by a user is typically performed as an elevated process. However, attempts by an application to modify default association behaviors at a machine level post-installation will be unsuccessful. Instead, defaults must be registered on a per-user level, which prevents multiple users from overwriting each other's defaults.
The hierarchical registry structure for file and protocol associations gives precedence to per-user defaults over machine-level defaults. These applications might experience unexpected results if another application is already registered as the per-user default. Use of Default Programs prevents this ambiguity and guarantees expected results on a per-user level. This section shows you the registry subkeys and values needed to register an application with Default Programs. It includes a full example.
Default Programs requires each application to register explicitly the file associations, MIME associations, and protocols for which the application should be listed as a possible default. You register the associations by using the following registry elements, which are explained in detail later in this topic under Registration Subkey and Value Descriptions :. The following example shows the registry entries for a fictional Contoso browser that is called WebBrowser:. An application must provide a specific ProgID.
Be sure to include all the information that is typically written into the generic default subkey for the extension. MP3 subkey. This ensures that if the user restores the. Overwriting might occur if the default subkey is the only source of that information. When you map a ProgID to a file name extension or protocol, an application can map one-to-one or one-to-many.
Because a different ProgID exists for each protocol, when you use protocols you enable each protocol to have its own execution string. If your MIME type is not intended to be viewed inline in a browser, this step can be omitted. This section describes the individual registry subkeys and values used in registering an application with Default Programs , as illustrated previously. The Capabilities subkey contains all the Default Programs information for a specific application.
