Explanation:
Two answers will return the correct results (the "WHERE CONVERT..." and "WHERE ... AND ... "answers).
The correct answer for Microsoft would be the answer that is most "efficient". Anybody have a clue as to
which is most efficient? In the execution plan, the one that I've selected as the correct answer is the query
with the shortest duration. Also, the query answer with "WHERE CONVERT..." threw warnings in the
execution plan...something about affecting CardinalityEstimate and SeekPlan.
I also found this article, which leads me to believe that I have the correct answer:

Microsoft begins To Publicly Launch Of Window 10 Share Points

Microsoft today launched a website dedicated to keeping track of Windows 10 Release Notes. For more features, improvements and changes the company has grown, now you can only visit the historic upgrade Windows 10.

"After listening to comments on the level of disclosure for Windows 10 updates, we decided to implement a new communication system, which updates the operating system," a Microsoft spokesperson told VentureBeat. "We now present the historical update Windows 10, a center for the release notes that accompany each update and serve as a historical record of notes from the previous version."

The "feedback" that Microsoft refers to fund amounts to complaints from users of Windows 10 who wanted to know more about what the company pushed to their devices. In the future, each updating of the list is a summary of significant developments with links to product details.

Because Windows 10 updates are cumulative, you may need to scroll down a bit to find exactly when something has changed. For now, Microsoft lists only two changes (also released today as part of the monthly Patch Tuesday cycle of Microsoft), as there are two windows 10 branches:

The first part of July launch (build 10240) and updated in November (build 10586) branch. We have introduced new features of the operating system in November after seeing, or "flighted", insiders with windows between July and November. Most customers have moved automatically from July to November Rama Rama. Windows 10 Professional, Enterprise and Education customers publishers may postpone updating the branch in November and stay in the SET's role in July - up to 10 years for some corporate customers.

Windows 10 is a service. As we wrote in our deep dive into how Microsoft is still working on Windows 10, Windows are started then new construction, even if the operating system launched in July 2015.

Microsoft Buys Company That Helps Crunch Messy Data

Acquisition may beef up Microsoft’s big data analytics push.

Microsoft acquires Meta Nautix, a startup founded by engineers from Google and Facebook to help more people crack big data.

The terms were not disclosed, but based in Palo Alto California Metanautix had raised about $ 7 million in venture funding from Sequoia Capital and others since its founding in 2012.

A founder Theo Vassilakis, who led the development of Dremel, a system open for consultation of scattered data between different systems code. Dremel has become the core (GOOG ^ 2.02%) BigQuery highly regarded data analysis service of Google. Its co-founder is Apostolos Lerios, former Facebook (FB 3.07%) senior engineer who worked in the photo service of this company, which is home to billions of our own photos and other images.

Metanautix applies the SQL standard (the initials stand structure query language) is used to quiz data from traditional relational data bases to the wild and woolly that do not fit this mold line and  Microsoft exam dumps columns. SQL is the standard language used to ask questions relational databases such as Oracle (ORCL ^ 2.08%) and Microsoft SQL Server.

Being able to apply this same tool to messy non-relational data, in theory it means that companies can learn a lot from various data sources at once. And tens of thousands of SQL and experts can apply their existing skills to new data types.

Therefore, a business analyst for a product manufacturer may wonder how a product sold in the second quarter, but also analyze the messages on Twitter or Facebook to see how customers liked them and they liked what they bought. A set of information is one thing at a traditional database, another set of data is the disruption of social networks.

In a blog post announcing the deal, Joseph Sirosh, Microsoft (MSFT ^ 2.85%) vice president of corporate data do not provide much in the way of detailed plans for Metanautix other than to say that Microsoft technology in the global data platform Microsoft. These include the SQL Server data and Cortana above the products of data analysis.

It was hard to know if the product of years Metanautix the Quest data engine, which cost HP, Shutterfly, and the University of Chicago and customers even be offered separately or whether its technology will be integrated into the Microsoft offering. I guess the latter.
