• Blocking telemetry in Office 365

    From https://twitter.com/milenkowski/status/1326865844215934979

    A hint for Office 365 Telemetry: Setting the undocumented (not officially supported) regvalue HKEY_CURRENT_USER\Software\Policies\Microsoft\office\common\clienttelemetry\DisableTelemetry to 1 (DWORD) disables the Office Telemetry module. This reduces the output of telemetry data.

    He also links to his report on the impact of the Office privacy settings (the diagnostic data levels) on the output of diagnostic data by Office.

    ERNW GmbH was tasked by the German Federal Office for Information Security (orig., ger., Bundesamt fur
    Sicherheit in der Informationstechnik (BSI)) with analyzing the output of telemetry data from Microsoft
    Office and provide recommendations on how to deactivate or minimize it (see Section 1.1 and Section 1.2).
