TLS Cipher Suites in Windows 7

That page states:

Windows 7, Windows 8, and Windows Server 2012 are updated by the Windows Update by the 3042058 update which changes the priority order. See Microsoft Security Advisory 3042058 for more information. 

That advisory states: 

The update added additional cipher suites to the default list on affected systems and improved cipher suite priority ordering. 

It has been available in Windows Update since Oct 2015.  Win7 only had one update actually named as a "Service Pack" ... SP1 in 2011.  After that there were many patches pushed via Windows Update.  The first "Convenience Rollup" of these patches was in July 2016.  If you just install that rollup the cipher updates will be included, and it will take care of any pre-reqs. See [July 21, 2016 — KB3172605](https://support.microsoft.com/en-us/

A Few Words from Jimmy Bogard

Jimmy Bogard is the creator/maintainer of Automapper.

Automapper Usage Guidelines

Excerpts from his blog:

• DO NOT use AutoMapper except in cases where the destination type is a flattened subset of properties of the source type

• AVOID using AutoMapper when you have a significant percentage of custom configuration in the form of Ignore or MapFrom. The "Auto" is for "automatic" and if it's not "Auto" then don't use this library, it will make things more, not less complicated.
