Microsoft has confirmed a new issue impacting Windows Server devices preventing the Microsoft Defender for Endpoint security solution from launching on some systems.
The enterprise endpoint security platform (previously known as Microsoft Defender Advanced Threat Protection or Defender ATP) might fail to start or run on devices with a Windows Server Core installation.
The known issue only impacts devices where customers have installed KB5007206 or later updates on Windows Server 2019 and KB5007205 or later updates on Windows Server 2022.
“After installing KB5007205 or later updates, Microsoft Defender for Endpoint might fail to start or run on devices with a Windows Server Core installation,” Microsoft explained on the Windows Server 2022 health dashboard.
As the company further revealed, this newly confirmed issue does not affect Microsoft Defender for Endpoint running on Windows 10 devices.
