Microsoft Confirms Windows Uses a Global Device Identifier You Can’t Fully Turn Off

Microsoft says Windows assigns a Global Device Identifier (GDID) that’s generated as part of how devices provision and work with Microsoft services. In response to user reports and questions, Microsoft indicated there is no setting to fully turn the GDID off. Critics argue that the ID can be used for device recognition and licensing or telemetry correlations, which they say makes tracking harder to avoid. Supporters argue it’s a practical identifier for device management and authentication. The key dispute is whether users can meaningfully control its creation and use.
