Title

Enhanced diagnostic data must be limited to the minimum required to support Windows Analytics. (Cat II impact)

Discussion

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 "Enhanced" level for telemetry includes additional information beyond "Security" and "Basic" on how Windows and apps are used and advanced reliability data. Windows Analytics can use a "limited enhanced" level to provide information such as health data for devices.

Check Content

If "Enhanced" level is enabled for telemetry, this must be configured. If "Security" or "Basic" are configured, this is NA. (See WN11-CC-000205). If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Policies\Microsoft\Windows\DataCollection\ Value Name: LimitEnhancedDiagnosticDataWindowsAnalytics Type: REG_DWORD Value: 0x00000001 (1)

Fix Text

Configure the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Data Collection and Preview Builds >> "Limit optional diagnostic data for Windows Analytics" to "Enabled" with "Enable Desktop Analytics collection" selected in "Options:".
