Windows 7 and 8.1: Mandatory telemetry data collection

Microsoft has recently launched two critical updates for Windows 7 and 8.1 that collect telemetry data.

From a technical point of view, both KB2952664 As well as the KB2976978, for systems running Windows 7 and Windows 8.1 respectively, were available for download, but as optional updates. However, both updates from optional were marked as critical by the company, which means they will be installed on all devices through Windows Update.

Similarly, Windows 7 and 8.1 acquire Microsoft telemetry services.

Microsoft states that both updates are "compatibility updates for Windows Update", explaining in a brief description that their purpose is to help collect some diagnostic data.

This update performs diagnostic tests on Windows systems that participate in the Windows Experience Improvement Program. Diagnostics assesses the compatibility status of the Windows ecosystem and helps Microsoft ensure application compatibility for all Windows updates.

The strange thing is that telemetry services are enabled on all computers, and not just those registered with Microsoft Windows Improvement Experience. So telemetry data is collected by all systems.

Let's say that according to the company, the telemetry data that is sent includes application errors and operating system information. Data can help the company improve Windows experience without collecting personal data.
