Defender for Endpoint - WIndows 10 1607 LTSB

Question

Hi all,

I am trying to onboard some Win10 1607 LTSB devices. From this MS article, it states 1607 LTSB is supported, however, I am unable to manage the devices

https://learn.microsoft.com/en-us/microsoft-365/security/defender-endpoint/minimum-requirements?view=o365-worldwide

In the Defender portal it says the devices can be onboarded

When I go into the device properties it says the OS is not supported. I have patched the machine with the latest Windows updates, but this has not made a difference. The "Windows" link in the below screenshot takes me to this page, where it mentions Windows 10 21H2 and 22H2, but nothing regarding 1607. https://learn.microsoft.com/en-us/purview/device-onboarding-overview#prepare-your-windows-devices

If I run the connectivity analyser tool on the device I get a warning saying the device does not have the minimum patch level. The below link takes me to this page https://learn.microsoft.com/en-us/mem/intune/protect/mde-security-integration?view=o365-worldwide#supported-platforms

Where it says the device must have Windows 10 KB5006738, which is only available for Windows 10 2004+

Can someone tell me is 1607 LTSB supported and if so how I can go about this, as the current MS documentation is not clear.

Thanks in advance.
