Windscribe has developed an open-source script called deGDID to remove Microsoft's Global Device Identifier (GDID) from Windows systems. The script functions as a firewall against the DeviceAdd endpoint, preventing Microsoft identity services from recognizing the machine as registered. It includes a flag, -Unprotect, to restore default settings if needed. Testing on a Windows 11 machine confirmed its effectiveness, with the -Status flag showing cached identifiers before removal. The tool is compatible with antivirus and endpoint protection but has limitations: it cannot delete keys stored on Microsoft's servers, cannot run on managed systems or domain-joined accounts, and Windows does not provide a built-in method to disable GDID. The identifier persists across IP addresses, regardless of VPN use. Windscribe notes that the script may disrupt certain Microsoft account functionalities, making it a partial solution rather than a comprehensive fix.
