Changes to Windows diagnostic data collection
Applies to
- Windows 10, version 1903 and newer
- The next version of Windows Server
Microsoft is committed to providing you with effective controls over your data and ongoing transparency into our data handling practices. As part of this effort, we are moving our major products and services to a model where data sent back to Microsoft from customer devices will be classified as either Required or Optional. We believe this will provide our customers with a simpler experience – information should be easier to find, easier to understand, and easier to act upon through the tools we provide.
This topic is meant for IT administrators and explains the changes Windows is making to align to the new data collection taxonomy. These changes are focused in two areas:
Note
You can test the behavioral changes now in Windows 10 Insider Preview build 19577 and later.
Summary of changes
In Windows 10, version 1903 and newer, you will see taxonomy updates in both the Out-of-box-experience (OOBE) and the Diagnostics & feedback privacy settings page. These changes are explained in the section named Taxonomy changes.
Additionally, in an upcoming release of Windows 10, we’re simplifying your diagnostic data controls by moving from four diagnostic data controls to three: Diagnostic data off, Required, and Optional. We’re also clarifying the Security diagnostic data level to more accurately reflect its behavior by changing it to Diagnostic data off. All of these changes are explained in the section named Behavioral changes.
Taxonomy changes
Starting in Windows 10, version 1903 and newer, both the Out-of-Box-Experience (OOBE) and the Diagnostics & feedback privacy setting pages will reflect the following changes:
- The Basic diagnostic data level is being labeled as Required.
- The Full diagnostic data level is being labeled as Optional.
Important
No action is required for the taxonomy changes, and your existing settings will be maintained as part of this update.
Behaviorial changes
In an upcoming release of Windows 10, we’re simplifying your diagnostic data controls by moving from four diagnostic data controls to three: Diagnostic data off, Required, and Optional. If your devices are set to Enhanced when they are upgraded, the device settings will be migrated to the more privacy-preserving setting of Required diagnostic data, which means that analytic services that leverage enhanced data collection may not work properly. For a list of services, see the section named, Services that rely on Enhanced diagnostic data, later in this topic. Administrators should read through the details and determine whether to apply these new policies to restore the same collection settings as they had before this change. For a list of steps, see the section named Configure a Windows 10 device to limit crash dumps and logs. For more information on services that rely on Enhanced diagnostic data, see Services that rely on Enhanced diagnostic data.
Additionally, you will see the following policy changes in an upcoming release of Windows 10:
| Policy type | Current policy | Renamed policy |
|---|---|---|
| Group Policy | Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds > Allow Telemetry
|
Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds > Allow Diagnostic Data
|
| Group Policy | Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds > Configure telemetry opt-in settings user interface | Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds > Configure diagnostic data opt-in settings user interface |
| Group Policy | Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds > Configure telemetry opt-in change notifications | Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds > Configure diagnostic data opt-in change notifications |
A final set of changes includes two new policies that can help you fine-tune diagnostic data collection within your organization. These policies let you limit the amount of optional diagnostic data that’s sent back to Microsoft.
- The Limit dump collection policy is a new policy that can be used to limit the types of crash dumps that can be sent back to Microsoft. If this policy is enabled, Windows Error Reporting will send only kernel mini dumps and user mode triage dumps.
- Group Policy: Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds > Limit Dump Collection
- MDM policy: System/LimitDumpCollection
- The Limit diagnostic log collection policy is another new policy that limits the number of diagnostic logs that are sent back to Microsoft. If this policy is enabled, diagnostic logs are not sent back to Microsoft.
- Group Policy: Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds > Limit Diagnostic Log Collection
- MDM policy: System/LimitDiagnosticLogCollection
Important
All of the changes mentioned in this section will not be released on versions of Windows, version 1809 and earlier as well as Windows Server 2019 and earlier.
Configure a Windows 10 device to limit crash dumps and logs
With the Enhanced diagnostic data level being split out into new policies, we're providing additional controls to manage what types of crash dumps are collected and whether to send additional diagnostic logs. Here are some steps on how to configure them:
- Choose to send optional diagnostic data by setting one of the following policies:
- Group Policy: Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds > Allow Diagnostic Data. Set the policy value to Send optional diagnostic data.
- MDM: System/AllowTelemetry. Set the policy value to 3.
- Enable the following Group Policy: Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds > Limit Dump Collection
- Enable the following Group Policy: Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds > Limit Diagnostic Log Collection
Services that rely on Enhanced diagnostic data
Customers who use services that depend on Windows diagnostic data, such as Microsoft Managed Desktop or Desktop Analytics, may be impacted by the behavioral changes when they are released. These services will be updated to address these changes and guidance will be published on how to configure them properly.
The following provides information on the current configurations:
