Installing and configuring SSM Agent on Windows Server instances
SSM Agent is installed by default on instances created from Windows Server 2016 and Windows Server 2019 Amazon Machine Images (AMIs), and on instances created from Windows Server 2008-2012 R2 AMIs published in November 2016 or later.
Windows Server AMIs published before November 2016 use the EC2Config service to process requests and configure instances.
Unless you have a specific reason for using the EC2Config service, or an earlier version of SSM Agent, to process Systems Manager requests, we recommend that you download and install the latest version of SSM Agent to each of your EC2 instances or hybrid instances that are configured for Systems Manager.
An updated version of SSM Agent is released whenever new capabilities are added to
Systems Manager or
updates are made to existing capabilities. If an older version of the agent is running
on an
instance, some SSM Agent processes can fail. For that reason, we recommend that you
automate
the process of keeping SSM Agent up-to-date on your instances. For information, see
Automate updates to SSM Agent. To be notified about SSM Agent updates, subscribe to the SSM Agent
