Microsoft's Global Device Identifier (GDID) is an internal marker that uniquely identifies each Windows installation across Microsoft services. It is a persistent device-level identifier that remains constant across supported services, and there is no option to disable or regenerate it manually. Windscribe has developed a free utility called deGDID to permanently remove the GDID from Windows systems and prevent its recreation. This tool operates by blocking Microsoft registration pathways and wiping local GDID-related states without altering system files. While it can remove the GDID from the local system, it cannot erase historical records linked to the device. Windscribe provides instructions for using the tool, which is compatible with Windows 10 version 22H2 and all versions of Windows 11 from 21H2 to 25H2. Users should be aware that disabling GDID generation may impact Microsoft services that rely on device identification, but the tool includes an undo feature to revert changes.
