Installing and configuring SSM Agent on EC2 instances for Windows Server
By default, SSM Agent is installed on the following Amazon Machine Images (AMIs):
-
Windows Server 2008-2012 R2 AMIs published in November 2016 or later
-
Windows Server 2016 and 2019
As of January 14, 2020, Windows Server 2008 is no
longer supported
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 Amazon Elastic Compute Cloud (Amazon 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
Automating updates to SSM Agent. To be notified about SSM Agent updates, subscribe to the SSM Agent
