Default Programs provides a set of APIs (deprecated in Windows. The API set also helps ISVs better manage their status as defaults. This topic is organized as follows: Introduction to Default Programs and Its Related API Set. Default Programs is primarily designed for applications that use standard file types such as . HTTP or mailto. 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: Restore all registered defaults for an application.

You can query for the default of a file association, protocol, or Start menu canonical verb. Launch a UI for a specific application where a user can set individual defaults. Remove all per- user associations. 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. Use of the associated API set can help an application function correctly under the user account control (UAC) feature introduced in Windows. Under UAC, an administrator appears to the system as a standard user, so that administrator cannot typically write to the HKEY. 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. Some applications include points in their code that temporarily elevate their rights when they claim defaults registered in HKEY. 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.
Registering an Application for Use with Default Programs. This section shows you the registry subkeys and values needed to register an application with Default Programs. It includes a full example.
This section contains the following topics: 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: HKEY.
Search the Internet and find exactly what you want in just seconds. Use integrated tabs and new phishing detectors to enhance your Internet experience. Be sure to include all the information that is typically written into the generic default subkey for the extension. For example, the fictional Litware media player provides the application- specific. HKEY. That subkey includes all the information in the generic default subkey. HKEY. This ensures that if the user restores the .
Litware player, the Litware player's information is intact and has not been overwritten by another application. In the Contoso example, Contoso. HTML points to a single Prog. ID that provides shellexecute information for the .
Because a different Prog. ID exists for each protocol, when you use protocols you enable each protocol to have its own execution string. When your MIME type can be viewed inline in a browser, the Prog. ID for the MIME type must contain the CLSID subkey that uses the class identifier (CLSID) of the corresponding application. This CLSID is used in a lookup against the CLSID in the MIME database that is stored in. HKEY. If your MIME type is not intended to be viewed inline in a browser, this step can be omitted. The placeholder %Application.
Capability. Path% refers to the registry path from either HKEY. This subkey contains the significant values shown in the following table. Value. Type. Meaning. Application. Description. REG. To enable a user to make an informed default assignment choice, an application must provide a string that describes the application's capabilities. Although the previous Contoso example assigns the description directly to the Application. Description value, applications typically provide the description as a resource that is embedded in a .
If Application. Description is not provided, the application does not appear in UI lists of potential default programs. Application. Name. REG. The name by which the program appears in the Default Programs UI. If this data is not provided by the application, the name of the executable program that is associated with the first registered Prog.
ID for the application is used in the UI. Application. Name must always match the name that is registered under Registered. Applications. Set this value to 1 to suppress the application from the list of programs in the Set your default programs dialog. If this value is 0 or not present, then the application appears in the list normally. These claims are stored as values, with one value for each extension. Associations point to an application- specific Prog.
ID instead of a generic Prog. ID. However, all associations are not required to point to the same Prog. ID. MIMEAssociations.
The MIMEAssociations subkey contains specific MIME types that are claimed by the application. These claims are stored as values, with one value for each MIME type. The value name for each MIME type must exactly match the MIME name that is stored in the MIME database. The value must also be assigned an application- specific Prog. ID that contains the corresponding CLSID of the application.
Startmenu. The Startmenu subkey is associated with the user- assignable Internet and E- mail entries in the Start menu. An application must register separately as a contender for those entries. For more information, see Registering Programs with Client Types. Note. The registry data associated with the E- mail entry is still used for the default MAPI client, but the registry data associated with the Internet entry is not used by Windows at all. If the user has chosen the application as the default and then chooses to restore all application defaults later, the application is restored to its Start menu position for that user. For more information and an illustration, see the Default Programs UI section later in this topic. The Startmenu subkey has two entries: Start.
Menu. Internet and Mail, which correspond to the canonical Internet and E- mail positions in the Start menu. An application assigns either Start. Menu. Internet or Mail a value equal to the name of the application's registered subkey under. HKEY. An application claiming the mail default should register as a MAPI handler under the following subkey: HKEY. Note that MAPI calls are still made to the application, and either fall through to the prior MAPI handler, or fail if no MAPI handler has been set. For more information, see Registering Programs with Client Types. Url. Associations.
The Url. Associations subkey contains the specific URL protocols that are claimed by the application. These claims are stored as values, with one value for each protocol. Each protocol must point to an application- specific Prog. ID instead of to a generic Prog. ID. As mentioned in the Contoso example, you can use a different Prog. ID for each protocol in order for each to have its own execution string.
Registered. Applications. The full subkey for Registered. Applications is: HKEY. The location is stored as a value whose name must match the name of the application. Full Registration Example.
This example shows the subkeys and values that are used in registering the fictional Litware media player. The example includes the Prog. ID entries in order to show how it all fits together. The following subkey shows the application- specific Prog. ID for the . mp. 3 MIME type: HKEY. When the browser is installed, Windows can present the user with a system notification through which the user can select the browser as the system default. This notification is shown when these conditions are met.
The browser's installer calls SHChange. Notify with the SHCNE. In other words, none of the following have been shown to the user: a system notification advertising the application, an Open. With flyout that contains the application, or the Set User Defaults (SUD) Control Panel page for the application. The following example shows the recommended registration code that the browser's installer should run after it writes its registry keys.
SHChange. Notify first notifies the system that new association choices are available. The SHChange. Notify call is required to ensure the proper functioning of system defaults. A Sleep statement then allows time for system processes to handle the notification. Notify. System. Of. New. Registration(). Note that the user can also change the default browser at any time through other mechanisms, including Set User Defaults in the Control Panel.
