Microsoft worked throughout the day to ensure we understood the attack and were taking all possible actions to protect our customers.” reads the advisory published by Microsoft.” 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.
