The tracking system based on the "Global Device Identifier" (GDID) embedded in Microsoft's Windows operating system has recently garnered significant attention. GDID is a persistent identifier at the device level that Microsoft employs to recognize individual Windows installations, and users are unable to deactivate it through standard settings. The cybersecurity and VPN service provider Windscribe has introduced a complimentary, open-source tool called deGDID, which it asserts can assist users in thoroughly removing GDID and stopping its reappearance. GDID is generated by the server once a user's device is initially linked to a Microsoft account. It is then stored in the local registry and monitored by several background services. Although GDID offers Microsoft ease in device management and service orchestration, its underlying privacy concerns have triggered widespread debate. At present, users do not have adequate means to manage how GDID is utilized.
