Update to add new cipher suites to Internet Explorer and Microsoft Edge in Windows

About this update

This article describes an update in which new TLS cipher suites are added and cipher suite default priorities are changed in Windows RT 8.1, Windows 8.1, Windows Server 2012 R2, Windows 7, or Windows Server 2008 R2. These new cipher suites improve compatibility with servers that support a limited set of cipher suites.

Note This is changing the default priority list for the cipher suites. If you have deployed a Group Policy in your environment that has an updated cipher suite priority ordering, this update won't affect those computers where the Group Policy is deployed.
