Summary
Trend Micro continues to offer support for Windows 2003. Windows 2003 reached end of life on July 14, 2015, however at this point in time, Deep Security will continue to support Windows 2003 with the Deep Security 10.0 agent.
Windows 2003 remains fully supported by the Trend Micro support team with the Deep Security 10.0 agent and we will continue to help customers if issues arise on this platform. However, given that the operating system is end of life, no new functionality will be added and there is a risk that customers may encounter an issue that cannot be fixed by Trend Micro. If this occurs, customers will be notified and the team will work with the customer to offer acceptable alternatives.
Customers who do not have the minimum OS build/patch of Microsoft Windows beginning mid-February of 2023 may encounter errors where the Trend Micro security agent service would fail to start after applying an updated binary signed with ACS. For more details refer to this
