More Information

This package updates the Diagnostic and Telemetry service to provide benefit for enterprises using Upgrade Analytics to plan and manage the Windows upgrade process. This update includes:

  • Support to enable upload of telemetry and download of settings in an authenticated proxy environment by impersonating the logged on user

  • Support to configure a specific proxy to upload telemetry and download settings

The Diagnostic and Telemetry service collects usage and diagnostics information from Windows. You can learn more about the Customer Experience Improvement Program (CEIP) here.

This update uses SSL (TCP Port 443) to download manifests and upload telemetry to Microsoft that uses the following DNS endpoints:

  • vortex-win.data.microsoft.com

  • settings-win.data.microsoft.com

This update contains the following two manifests that are used by the service.

  • telemetry.ASM-WindowsDefault.json

  • utc.app.json

Registry informationImportant
Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.

By default on Windows 8.1, support for sending usage and diagnostics information through an authenticated proxy is disabled. When the setting isn't disabled (0x0) through the following registry key, the Diagnostic and Telemetry service will impersonate a logged on user to authenticate with the proxy to send the information. If you are using Upgrade Analytics in a network environment that uses an authenticated proxy, we recommends configuring this setting to 0x0.

  1. Locate and then select the registry subkey HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection

  2. On the Edit menu, point to New, and then click DWORD Value.

  3. Type DisableEnterpriseAuthProxy, and then press the Enter key.

  4. In the Details pane, right-click DisableEnterpriseAuthProxy, and then click Modify.

  5. In the Value data box, type 0 (not disabled) or 1 (disabled), and then click OK.

You can also configure the Diagnostic and Telemetry service to forward usage and diagnostics information to a specific proxy server using the following registry path. You can specify the FQDN or IP address of the proxy server and optionally a port number.

  1. Locate and then select the registry subkey HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection

  2. On the Edit menu, point to New, and then click String Value.

  3. Type TelemetryProxy, and then press the Enter key.

  4. In the Details pane, right-click TelemetryProxy, and then click Modify.

  5. In the Value data box, type server:port, and then click OK.
