I assume most of us have already heard of the WannCrypt worm that was been causing havoc in something like 74 countries with the bulk of the infected systems being run on either out of lifecycle operating systems and anything below Win 10 that isn't up to date in the last couple of months. This is a ransomware worm that targets all document files on the infected drive and encrypts them. Once completed it forces a blue screen and reboot followed up with a message that to recover your files you must pay a certain amount of bitcoin to have your files decrypted.
Microsoft has released hotfixes for both currently supported systems and "out of lifecycle" systems including XP (x86 - x64 - embedded) Win 8 (x86 - x64 - Win 8.1 is supported by auto update) and Server 2003. Here's the link to the Microsoft Technet page with links to more information and directly download the patches for the "out of lifecycle" systems.
Customer Guidance for WannaCrypt attacks

Microsoft solution available to protect additional products
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.
Details are below.
