Official Microsoft Post,

Today many of our customers around the world and the critical systems they depend on were victims of malicious “WannaCrypt” software. Seeing businesses and individuals affected by cyberattacks, such as the ones reported today, was painful. Microsoft worked throughout the day to ensure we understood the attack and were taking all possible actions to protect our customers. This blog spells out the steps every individual and business should take to stay protected. Additionally, we are taking the highly unusual step of providing a security update for all customers to protect Windows platforms that are in custom support only, including Windows XP, Windows 8, and Windows Server 2003. Customers running Windows 10 were not targeted by the attack today.

We also know that some of our customers are running versions of Windows that no longer receive mainstream support. That means those customers will not have received the above mentioned Security Update released in March. Given the potential impact to customers and their businesses, we made the decision to make the Security Update for platforms in custom support only, Windows XP, Windows 8, and Windows Server 2003, broadly available for download

Hello there! I could have sworn I’ve been to this site before but after
browsing through many of the articles I realized it’s new to me.
Anyways, I’m certainly happy I came across it and I’ll be book-marking it and checking back often!

Since Windows 10 would normally have installed this patch when it was first released in March 2017, it's most likely that the 2nd cause listed in the Microsoft Support article excerpt below applies.

This particular update only typically needs to be manually installed on older, unsupported Windows operating system versions such as Windows XP, 8.0 or in the less common case where the Windows Updates have been failing to install properly.

To determine whether this is the case, you may view the installed updates by following the method for your specific operating system version found in this Windows Update: FAQ article under the section heading titled; How do I see installed updates on my PC?

Note that the item listed that includes the update for Windows 10 originally would have been the Cumulative Update dated March 14, 2017—KB4013429. However, this would likely also have been superseded and so replaced by either a later cumulative update or the Creators Update by now, since these include all previously delivered updates.

For either Windows 7 or 8.1, it would have been included in the March 2017 Security Monthly Quality Rollup for that specific version of Windows, typically installed on or shortly after the March 14th release date.
