The majority of customers have automatic updates enabled and will not need to take any action because protections will be downloaded and installed automatically. If you're unsure if you have automatic updates, or you haven't enabled Automatic Update, now is the time.

For those manually updating, we strongly encourage you to apply this update as quickly as possible following the directions in the released security bulletin.

We have made the decision to issue a security update for Windows XP users. Windows XP is no longer supported by Microsoft, and we continue to encourage customers to migrate to a modern operating system, such as Windows 7 or 8.1. Additionally, customers are encouraged to upgrade to the latest version of Internet Explorer, IE 11.
