While the provider (through logic in the <b class="bterm">Registration</b> method) can programmatically select which services to install, the user does not have an equivalent option in the <b class="bterm">Research</b> task pane user interface to select or exclude individual services at the time of registration. In some cases, the provider may choose to install services, but not to activate them, by setting their <b class="bterm">Display</b> setting to "Off." The user can activate or deactivate services at any time, from the <b class="bterm">Research Options</b> dialog box.</p><p><a href="#" class="DropDown" onclick="Outline2()" onkeypress="Outline2()"><img border="0" src="blueup.gif" alt="Show">How to control the installation of default services</a></p><div id="ExpCol" class="collapsed" border="0"><p>Research services are made available through a provider, which can host multiple services. Microsoft Office 2003 applications connect to a provider through its URL and receive a list of available services from the provider. By default, all Office 2003 installations are configured to check Microsoft's provider for new Microsoft services and for third-party services that Microsoft lists, and to install specific services by default. Organizations can also create their own providers, exposing whichever services they want.</p><p>The normal registration process registers research services for the current user only, under the <b class="bterm">HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\Research\Sources</b> registry subkey. To specify which services are installed by default, you can create a set of subkeys under <b class="bterm">HKEY_LOCAL_MACHINE</b> that define those services. By default, no subkeys exist at <b class="bterm">HKEY_LOCAL_MACHINE\Software\Microsoft\Office\11.0\Common\Research\Sources</b>. Creating a list of provider and service subkeys in this location causes Office to modify its normal procedure for the initial installation of services. Before contacting Microsoft's discovery servers and any registered discovery servers, and installing default services from those sources, Office finds these subkeys located at <b class="bterm">HKEY_LOCAL_MACHINE</b> and copies them to <b class="bterm">HKEY_CURRENT_USER</b>. Copying the subkeys results in the services that you specified being installed for the user. This process is called "propagation."</p><p><b>Note</b> The values of the <b class="bterm">NoAdd</b>, <b class="bterm">NoDiscovery</b>, and <b class="bterm">DiscoveryNeedOptIn</b> registry entries do not prevent propagation. For more information about these entries, see <a href="rsregAdministrativeOptions.htm" id="HV01083009" lcid=" ">Administrative Option Settings</a>.</p><p>The subkeys and entries created by the administrator under <b class="bterm">HKEY_LOCAL_MACHINE</b> should have the same names and format as those normally installed under <b class="bterm">HKEY_CURRENT_USER</b>.
