Installing a protocol handler involves copying the DLL(s) to an appropriate location in the Program Files directory, and then registering the protocol handler through the registry. The installation application can also add a search root and scope rules to define a default crawl scope for the Shell data source.
Windows Search uses URLs to uniquely identify items in the hierarchy of your Shell data source. The URL that is the first node in the hierarchy is called the search root; Windows Search will begin indexing at the search root, requesting that the protocol handler enumerate child links for each URL.
The Windows Search Indexer trims the final slash from URLs. As a result you cannot rely on the existence of a final slash to identify a directory versus an item. Your protocol handler must be able to handle this URL syntax. Ensure that the protocol name that you select to identify your Shell data source does not conflict with current ones. We recommend this naming convention: companyName.scheme.
The SearchProtocol interfaces initialize and manage your protocol handler UrlAccessor objects. The ISearchProtocol2 interface is an optional extension of ISearchProtocol, and includes an extra method to specify more information about the user and the item.
The UrlAccessor object is instantiated and initialized by a SearchProtocol object. The IUrlAccessor interfaces provide access to important pieces of information through the methods described in the following table.
The IProtocolHandlerSite interface is used to instantiate a filter handler, which is hosted in an isolated process. The appropriate filter handler is obtained for a specified persistent class identifier (CLSID), document storage class, or file name extension. The benefit of asking the host process to bind to IFilter is that the host process can manage the process of locating an appropriate filter handler, and control the security involved in calling the handler.
If you are implementing a hierarchical protocol handler, then you must implement a filter handler for a container that enumerates child URLs. A filter handler is an implementation of the IFilter interface. The enumeration process is a loop through the IFilter::GetChunk and IFilter::GetValue methods of the IFilter interface; each child URL is exposed as the value of the property.
Returning PKEY_Search_UrlToIndexWithModificationTime is more efficient because the indexer can immediately determine whether the item needs to be indexed without calling the ISearchProtocol::CreateAccessor and IUrlAccessor::GetLastModified methods.
A container IFilter component should always enumerate all child URLs even if the child URLs have not changed, because the indexer detects deletions through the enumeration process. If the date output in a PKEY_Search_UrlToIndexWithModificationTime indicates that the data has not changed, the indexer does not update the data for that URL.
Installing protocol handlers involves copying the DLL(s) to an appropriate location in the Program Files directory, and then registering the DLL(s). Protocol handlers should implement self-registration for installation. The installation application can also add a search root, and scope rules to define a default crawl scope for the Shell data source, which is discussed in Ensuring that Your Items are Indexed at the end of this topic.
After you have implemented your protocol handler, you must specify which Shell items your protocol handler is to index. You can use the Catalog Manager to initiate re-indexing (for more information, see Using the Catalog Manager). Or you can also use the Crawl Scope Manager (CSM) to set up default rules indicating the URLs that you want the indexer to crawl (for more information, see Using the Crawl Scope Manager and Managing Scope Rules). You can also add a search root (for more information, see Managing Search Roots). Another option available to you is to follow the procedure in the ReIndex sample in Windows Search Code Samples.
The ISearchCrawlScopeManager interface provides methods that notify the search engine of containers to crawl and/or watch, and items under those containers to include or exclude when crawling or watching. In Windows 7 and later, ISearchCrawlScopeManager2 extends ISearchCrawlScopeManager with the ISearchCrawlScopeManager2::GetVersion method that gets the version, which informs clients whether the state of the CSM has changed.
Applications and services that are written by using WinHTTP for Secure Sockets Layer (SSL) connections that use the WINHTTP_OPTION_SECURE_PROTOCOLS flag can't use TLS 1.1 or TLS 1.2 protocols. This is because the definition of this flag doesn't include these applications and services.
This update adds support for DefaultSecureProtocols registry entry that allows the system administrator to specify which SSL protocols should be used when the WINHTTP_OPTION_SECURE_PROTOCOLS flag is used.
This can allow certain applications that were built to use the WinHTTP default flag to be able to leverage the newer TLS 1.2 or TLS 1.1 protocols natively without any need for updates to the application.
This is the case for some Microsoft Office applications when they open documents from a SharePoint library or a Web Folder, IP-HTTPS tunnels for DirectAccess connectivity, and other applications by using technologies such as WebClient by using WebDav, WinRM, and others.
This update requires that the Secure Channel (Schannel) component in Windows 7 be configured to support TLS 1.1 and 1.2. As these protocol versions are not enabled by default in Windows 7, you must configure the registry settings to ensure Office applications can successfully use TLS 1.1 and 1.2.
Important If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see Add language packs to Windows.
To apply this update, the DefaultSecureProtocols registry subkey must be added.
Note To do this, you can add the registry subkey manually or install the "Easy fix" to populate the registry subkey.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, see How to back up and restore the registry in Windows.
When an application specifies WINHTTP_OPTION_SECURE_PROTOCOLS, the system will check for the DefaultSecureProtocols registry entry and if present override the default protocols specified by WINHTTP_OPTION_SECURE_PROTOCOLS with the protocols specified in the registry entry. If the registry entry is not present, WinHTTP will use the existing operating system defaults for Win WINHTTP_OPTION_SECURE_PROTOCOLS HTTP. These WinHTTP defaults follow the existing precedence rules and are overruled by SCHANNEL disabled protocols and protocols set per application by WinHttpSetOption.
Note The hotfix installer doesn't add the DefaultSecureProtocols value. The administrator must manually add the entry after determining the override protocols. Or, you can install the "Easy fix" to add the entry automatically.
Per the TLS-SSL Settings article, for TLS 1.1 and 1.2 to be enabled and negotiated on Windows 7, you MUST create the "DisabledByDefault" entry in the appropriate subkey (Client) and set it to "0". These subkeys will not be created in the registry since these protocols are disabled by default.
The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed in the "Additional file information" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
I'm building my first project in Laravel and trying to use Elixir, using homestead on Windows 8.1. I've hit the known npm/vagrant issue of too-long-path-names: -to-fix-npm-install-errors-on-vagrant-on-windows-because-the-paths-are-too-long/
Is there any way to install a particular Cisco VPN protocol (eg. DTLS) in Windows 10's native VPN client (as shown in the screenshot)? I found apps for other protocols (Eg. Pulse Connect) in the Microsoft Store which integrate into the Windows VPN interface, but none for Cisco. The AnyConnect software itself works fine on my computer but I'd like to find a way to integrate it into Windows 10, even if it's super hacky.
I know this is like a year late, but if anyone else looks for the answer, you can install the AnyConnect UWP from the Microsoft Store, and then you can select the Cisco AnyConnect provider within the Windows settings.
The symptom was described in a prior post linked below but in that case the user seemed to be missing the actual driver, mslldp.sys. In my case I already have that file in my Windows/System32/drivers folder. Microsoft LLDP protocol driver Uninstalled and Can't Reinstall
On Windows 7: The Web Client would NOT start automatically if it is stopped. Instead, the protocol app installer and protocol application itself (when opening a document) verifies the status of the Web Client service and offers to start the service in case it is not running. Starting the Web Client service requires administrative privileges, including when installing with the 'Only for me' option. The Web Client service will be also configured to automatically start when Windows starts.
