In Windows 8 there is only one way to do this. You should add your app to Defaults Applications. Then use Default Programs to ask an user to set associations. Unsure the old way with registry editing now is not availabled. In Windows 8 was added Hash variable to UserChoice registry key. It is unique for user and app. If it is wrong YourAppName is not be started by default but Windows 8 ask to choose application.

Short instruction how to add app to Default Programs. Full guide there http://msdn.microsoft.com/en-us/library/windows/desktop/cc144154%28v=vs.85%29.aspx Add to registry

key: "HKLM\Software\RegisteredApplications" name: "YourAppName" value: "Sofware\YouCompany\YourAppName\Capabilities"
key: "HKLM\Sofware\YouCompany\YourAppName\Capabilities" name: "ApplicationDescription" value: "just a description"
key: "HKLM\Sofware\YouCompany\YourAppName\Capabilities" name: "ApplicationName" value: "YourAppName"
key: "HKLM\Sofware\YouCompany\YourAppName\Capabilities\FileAssociations" name: ".txt" value: "Progid.txt"

Now YourAppName added to Default Programs

Need to call dialog with application file associations. It can be done with IApplicationAssociationRegistrationUI::LaunchAdvancedAssociationUI http://msdn.microsoft.com/en-us/library/windows/desktop/bb776329%28v=vs.85%29.aspx

    IApplicationAssociationRegistrationUI *applicationAssociationRegistrationUI = 0;

    CoCreateInstance(CLSID_ApplicationAssociationRegistrationUI,
                     0,
                     CLSCTX_INPROC_SERVER,
                     IID_IApplicationAssociationRegistrationUI,
                     (LPVOID*)&applicationAssociationRegistrationUI);

    if (applicationAssociationRegistrationUI)
        applicationAssociationRegistrationUI->LaunchAdvancedAssociationUI(L"YourAppName");
