Deletes all instances of Microsoft's GDID and prevents minting of new ones

Microsoft's Global Device Identifier (GDID) is a machine-level tracking identifier that persists even on local Windows accounts, and a new tool (deGDID) enables IT organizations to remove existing GDIDs and block future creation—though doing so will disable MSA sign-in, Microsoft Store, OneDrive, and Xbox authentication. For CIOs managing personal or unmanaged Windows installations, this represents a critical privacy control but comes with significant operational trade-offs, including breaking cloud-connected services and requiring ongoing maintenance as Windows updates occur. Organizations must weigh user privacy requirements against dependency on Microsoft's identity and cloud services before deploying such controls.
