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.
This subkey contains the significant values shown in the following table. The FileAssociations subkey contains specific file associations that are claimed by the application.
These claims are stored as values, with one value for each extension. However, all associations are not required to point to the same ProgID. These claims are stored as values, with one value for each MIME type.
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. As of Windows 7, there are no longer Internet and E-mail entries in the Start menu. 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.
By associating the Start menu registration of an application with its Default Programs registration, the application appears as a potential default in the Set associations UI. 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. Under Windows 7, while there is no longer an E-mail canonical position in the Start menu, this subkey continues to be used for the default MAPI client.
An application claiming the mail default should register as a MAPI handler under the following subkey:. If a mail client cannot support MAPI but still wants to contend for the Start menu E-mail canonical position, it can register a command line under the following subkey:. These entries allow the application to be launched from the Start menu's E-mail position.
These claims are stored as values, with one value for each protocol. As mentioned in the Contoso example, you can use a different ProgID for each protocol in order for each to have its own execution string. This subkey provides the operating system with the registry location of the Default Programs information for the application.
The location is stored as a value whose name must match the name of the application. This example shows the subkeys and values that are used in registering the fictional Litware media player. The example includes the ProgID entries in order to show how it all fits together. Next is the application-specific ProgID that associates the Litware program with the. Lastly, this example registers the location of the Litware Default Programs registration.
Browser registration must follow the best practices outlined in this topic. 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 following example shows the recommended registration code that the browser's installer should run after it writes its registry keys. Normally this is not a problem - MS Word, for example, lets you choose where to store documents, templates and so on.
But the News app in Windows 8. I could delete it, of course, but I am unable to automatically store new news items anywhere but where the OS put the program in the first place. So I saw no option, really, but to delete the app. Not the effect I think MS is going for! We do not recommend you to change the default location. You can certainly change the default location of other applications. As far as your concern about the saving space, you can try to remove store cache every month so that it may remove temporary caches.
You can now browse the Store for apps. Hope the information helps. I'm afraid your reply confirms my already taken action; I appreciate the reply but really, 'we do not recommend you to change the default location' doesn't really work for me, as it will take up SSD space I don't want it to.
The cure - remember to clear out the cache every so often - is a frankly kludgy workaround; I find a far better solution is to not install apps that don't give me the option to store large quantities of data where I prefer.
News is the only app I've come across where it's a problem, so it is no more. Not, to be fair, a huge problem as there are so many more user-centric news aggregators out there. Hello all, Is there a way to change the location of the apps default installation folder in Windows 8.

This option lets you set a default app for that category. At the bottom of the screen there are two more options: Choose default apps by file type and Choose default apps by protocol.
In both cases the default apps will be organized by file types or protocol and you can also change them by clicking on the current default app and selecting another one from the pop-up menu.
