SSM Agent is also installed, by default, on Windows Server 2016, 2019 and 2022 AMIs.You must manually install SSM Agent on Amazon EC2 instances created from other versions of Windows AMIs, including images imported to AWS. You can install SSM Agent by adding user data to an Amazon EC2 Windows instance before the launch. You can keep the SSM Agent up to date by activating SSM Agent auto update under Fleet Manager settings.As of January 14, 2020, Windows Server 2008 is no longer supported for feature or security updates from Microsoft. Legacy AMIs for Windows Server 2008 and 2008 R2 still include version 2 of SSM Agent preinstalled. AWS Systems Manager no longer officially supports 2008 versions, and no longer updates the agent for these versions of Windows Server. SSM Agent version 3.0 might not be compatible with all operations on Windows Server 2008 and 2008 R2.
