Vulnerability discussion

Office Diagnostics is used to improve the user experience by periodically downloading a small file to the computer with updated help information about specific problems. If Office Diagnostics is enabled, it collects information about specific errors and the IP address of the computer. When new help information is available, that help information is downloaded to the computer that experienced the related problems. Office Diagnostics does not transmit any personally identifiable information to Microsoft other than the IP address of the computer requesting the update. By default, users have the opportunity to opt into receiving updates from Office Diagnostics the first time they run a 2010 Office application. If your organization has policies that govern the use of external resources such as Office Diagnostics, allowing users to opt in to this feature might cause them to violate these policies.
