• Windows 10 Enterprise: Does setting telemetry to zero disable cumulative updates?

    A very interesting post this morning from Günter Born. In a nutshell:

    • If you’re running Win10 Enterprise
    • And you aren’t connected to an update server
    • And you set the level of telemetry to “Security data only” (HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\DataCollection\AllowTelemetry set to 0)

    You don’t get any cumulative updates.

    Sounds like a bug to me. Can anyone out there confirm?

    UPDATE: @teroalhonen pointed me to the Microsoft documentation for the AllowTelemetry setting:

    Security level

    The Security level gathers only the diagnostic data info that is required to keep Windows devices, Windows Server, and guests protected with the latest security updates. This level is only available on Windows Server 2016, Windows 10 Enterprise, Windows 10 Education, Windows 10 Mobile Enterprise, and Windows IoT Core editions.


    If your organization relies on Windows Update for updates, you shouldn’t use the Security level. Because no Windows Update information is gathered at this level, important information about update failures is not sent. Microsoft uses this information to fix the causes of those failures and improve the quality of our updates.

    Windows Server Update Services (WSUS) and System Center Configuration Manager functionality is not affected at this level, nor is diagnostic data data about Windows Server features or System Center gathered.

    Sure enough — it’s not a bug, it’s a feature!
