Windows Server 2025 Telemetry must be configured to limit diagnostic data sent to Microsoft.

| Finding ID | Version | Rule ID | IA Controls | Severity |

| Description | ||||
| Some features may communicate with the vendor, sending system information or downloading data or components for the feature. Limiting this capability will prevent potentially sensitive information from being sent outside the enterprise. The "send required diagnostic data" option for Allow Diagnostic Data configures the lowest amount of data, effectively none outside of the Malicious Software Removal Tool (MSRT), Defender, and Diagnostic Data client settings. "Optional Diagnostic Data" sends basic diagnostic and usage data and may be required to support some Microsoft services. | ||||
