HTTP Strict Transport Security (HSTS)

HTTP Strict Transport Security (HSTS), specified in RFC 6797, allows a website to declare itself as a secure host and to inform browsers that it should be contacted only through HTTPS connections. IIS 10.0 Version 1709 introduces turn-key support for enabling HSTS without the need for error-prone URL rewrite rules.

Container Enhancements

IIS 10.0 Version 1709 introduces improvements that allow you to run the IIS worker process (w3wp.exe) directly as well as changes to the Central Certificate Provider (CCS) that makes it more amenable for running in containers.

IIS 10.0 introduced the IIS Administration PowerShell cmdlets. Version 1709 ships with iterative improvements and three new cmdlets: Get-IISSiteBinding, New-IISSiteBinding, and Remove-IISSiteBinding. Additionally, we've done work to ship the latest version of IISAdministration on PowerShell Gallery available for use with Windows Server 2012 and above.
