When a user sends a query to a research service provider, the response can include an optional revision number for the current version of the service available from the provider. If this version number is different from the version registered on the user's computer, Microsoft® Office 2003 prompts the user to update the service.</p>
<p>The currently registered revision number is stored on the user's computer as the DWORD value of the <b class="bterm">Revision</b> entry under the <b class="bterm">HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\Research\Sources\{ProviderID}</b> subkey.
