Set Connect Windows devices to MS defender for endpoint to on in the MS endpoint admin center

Hello all,

I found in the documentation  this description:

Return to Microsoft Defender for Endpoint page in the Microsoft Endpoint Manager admin center.

1. To use Defender for Endpoint with compliance policies, configure the following under MDM Compliance Policy Settings for the platforms you support:

   • Set Connect Android devices to Microsoft Defender for Endpoint to On
   • Set Connect iOS devices to Microsoft Defender for Endpoint to On
   • Set Connect Windows devices to Microsoft Defender for Endpoint to On

But I don't find any information, what happens after I set ON for the windows devices?  Is there an explantion what does it means? 

thanks for your support

regards

Carsten
