Microsoft announced a series of new changes to Windows 10 that aims to make telemetry collection a more meaningful process and allow users to make better choices based on the level they choose. Currently, diagnostic data has four set levels, namely Security, Basic, Enhanced, and Complete. Microsoft has abandoned the “enhanced” level and renamed other versions to a more streamlined approach.
The Security level will be called Close Diagnostic Data, and the Basic configuration will become “Required Diagnostic Data.” The full level is the choice that insiders need to continue to receive builds in the Windows Insider program, which has been renamed Optional Diagnostic Data.
As part of this change, any device previously set to Enhanced will default to Basic. This will cause some devices to fail to receive data as expected. Enabling Optional Diagnostic Data sets the device to diagnostic level 3 (previously Full) and causes the user to return the data as expected.
Microsoft has also made a special distinction between the telemetry data of commercial users, with the option to send custom diagnostic data, and in the future, it will provide more granular Group Policy settings to configure the data collected within the organization.
These changes took effect with the release of Windows 10 Build 19577 in the Windows Insider program, and Microsoft says everyone must enable optional diagnostic data to receive more builds.
On devices that have joined AAD or set telemetry to “enhanced” and “domain-joined”, the only way is for the administrator to set the diagnostic data policy to Full, otherwise the Insider program will not provide a new build.
The next public release for Windows 10 users is the 2004 release, which is expected to be released in April or May, according to Microsoft’s typical spring feature update schedule.
