| February 16 2026 | Recommendation | Upcoming deprecation <br> (March 19, 2026) | The preview recommendation `Machines should be configured securely (powered by MDVM)`, which applied to Window machines, is set for deprecation. The recommendation is set to be replaced by the following OS-specific recommendations, which include Linux support using Guest configuration: <br><br> - **Vulnerabilities in security configuration on your Linux machines should be remediated (powered by Guest Configuration)** <br><br> - **Vulnerabilities in security configuration on your Windows machines should be remediated (powered by Guest Configuration)**.<br><br> These replacement recommendations are already available in Defender for Cloud. <br><br> If you have any governance rules, reports, or workflows that reference the deprecated recommendation, update them to use the replacement recommendations. To ensure the new recommendations can assess your machines, verify that the required prerequisites are in place: <br><br> - **Azure machines** should have the [Azure Machine Configuration extension](/azure/virtual-machines/extensions/guest-configuration) installed. <br> - **Non-Azure machines** should be onboarded via [Azure Arc](/azure/azure-arc/servers/overview), which includes the Machine Configuration extension by default. |
