Disable gradual rollout of Microsoft Defender updates.
Supported on SUPPORTED_Windows_10_RS1 (defined in the Windows templates)
What it does
Enable this policy to disable gradual rollout of Defender updates. Current Channel (Broad): Devices set to this channel will be offered updates last during the gradual release cycle. Best for datacenter machines that only receive limited updates. Note: This setting applies to both monthly as well as daily Defender updates and will override any previously configured channel selections for platform and engine updates. If you disable or do not configure this policy, the device will remain in Current Channel (Default) unless specified otherwise in specific channels for platform and engine updates. Stay up to date automatically during the gradual release cycle. Suitable for most devices.

- The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
- Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
