This update provides support for Transport Layer Security (TLS) 1.1 and TLS 1.2 in Windows Server 2012, Windows 7 Service Pack 1 (SP1), and Windows Server 2008 R2 SP1.

About this update

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.

This update will not change the behavior of applications that are manually setting the secure protocols instead of passing the default flag.

File Information

The English (United States) version of this software update installs files that have the attributes that are listed in the following tables.

Notes

  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.

    Version

    Product

    Milestone

    Service branch

    6.1.760 1.23 xxx

    Windows 7 or Windows Server 2008 R2

    SP1

    LDR

  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.

  • 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.
