Windscribe has introduced deGDID, a tool aimed at countering the Global Device Identifier (GDID), a Windows tracking mechanism that can trace user activities despite VPN usage. The GDID is a persistent identifier assigned to individual Windows installations, remaining unchanged through updates but reset during a clean reinstallation. It can link telemetry data and browsing history to a specific device, allowing Microsoft to track users across different sessions.
deGDID works by modifying the hosts file and implementing firewall rules to prevent Windows from retrieving the GDID and to erase local identity artifacts. Users can download and execute the degdid.ps1 script from GitHub in PowerShell, which includes options for checking status, blocking the GDID, and reversing changes. The tool is not designed for corporate machines and may disrupt access to services like Xbox and Outlook due to its firewall rules. Windscribe warns that it cannot guarantee the complete eradication of GDID pathways or existing records held by Microsoft.
