Windows 7 October Upcate Question

This morning I get an update notification for my Win 7 system.

After doing the research for

with particular interest in this section of the page:

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 information
Important 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 7 SP1, support for sending usage and diagnostics information through an authenticated proxy is not disabled (0x0), and the Diagnostic and Telemetry service will impersonate a logged-on user to authenticate with the proxy to send information. You can configure this behavior by using the following registry subkey:

Locate and then select the registry subkey
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection
On the Edit menu, point to New, and then click DWORD Value.
Type DisableEnterpriseAuthProxy, and then press the Enter key.
In the Details pane, right-click DisableEnterpriseAuthProxy, and then click Modify.
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 by using the following registry subkey. You can specify the FQDN or IP address of the proxy server and optionally a port number.

Locate and then select the registry subkey
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DataCollection
On the Edit menu, point to New, and then click String Value.
Type TelemetryProxy, and then press the Enter key.
In the Details pane, right-click TelemetryProxy, and then click Modify.
In the Value data box, type server:port, and then click OK.

My quesion is about setting the registry informaion.. has anyone doen this and knows what the heck happens with setting the registy information?

TIA
