Starting May 10, 2021, Windows 7 and Windows Server 2008 R2 will no longer be supported by Worry-Free Business Security Services (WFBS-SVC). Aside from the main reason that these operating systems have reached Microsoft’s End-Of-Support, another reason for this change is because it has already been announced that the Microsoft Trusted Root Program is ending the support for cross-signed root certificates with kernel-mode signing capabilities.
For more information, refer to this Microsoft article: 2019 SHA-2 Code Signing Support requirement for Windows and WSUS.
Users can still install Security Agent on the machines running on these operating systems but the agent build which will be deployed will be the agent build included in the April 12 hotfix release that includes SHA1 and SHA2 support.
Trend Micro recommends users to upgrade to the latest supported version of the OS as soon as possible for the Security Agents to receive latest hotfix releases and bug fixes. Other functions, including pattern update, will still work as normal if the license is valid.
If you have any questions or concerns, please contact Trend Micro Technical Support or your assigned Customer Service Manager.
