Microsoft Defender Antivirus on Windows 10 and Windows 11 will be shipping with a new service called Microsoft Defender Core service. The rollout will occur in stages, starting with a preview in November 2023 and worldwide rollout in April 2024. To prepare, users need to update the Platform Update to the latest version and allow specific URLs. If using an Application Control application or running a 3rd party AV and/or EDR, add the Microsoft Defender Core Service process to the allowed list.
