What does deGDID do to block Windows device tracking?
deGDID, created by Windscribe, is a free and open source script designed to stop Microsoft's Global Device Identifier (GDID) from tracking your device on Windows. Unlike most privacy measures, GDID operates below the network level—meaning traditional VPNs and proxy tools are ineffective against it. deGDID works by deleting the cached GDID in your system's registry and changing key registry permissions so Windows cannot reissue the identifier. It also blocks Microsoft's internal DeviceAdd endpoint, further severing the link between your hardware and Microsoft's cloud services.
Which Microsoft services break when using deGDID?
Removing GDID comes with significant functional trade-offs. Most notably, deGDID breaks some core Microsoft cloud authentication services. For example, login.live.com and certain account verification processes will fail after the script runs. This means that features relying on Microsoft's unified authentication or device recognition—like account recovery, some app sign-ins, and authorized cloud synchronization—may stop working. However, other services, such as login.microsoftonline.com (often used for business and education accounts), still function. Some Microsoft apps may return connection errors, though many online games and third-party apps remain unaffected. Users focused on privacy must weigh these losses against the benefits.
Can deGDID fully remove all tracking data?
While deGDID blocks new tracking IDs from being created locally, it cannot erase any identifiers previously collected and stored by Microsoft servers. Any GDID information already uploaded to the cloud remains accessible to Microsoft indefinitely. Additionally, deGDID cannot run on company-managed or domain-joined systems, meaning its use is mostly limited to personal devices. Windows does not offer any official method for disabling GDID, so tools like this are currently the only available workaround for advanced users.
Who should consider using deGDID—and who should avoid it?
deGDID is best for privacy-focused individuals who want a technical solution to stop persistent device-level tracking by Microsoft on unmanaged Windows machines. It's especially relevant for security professionals, privacy advocates, and researchers concerned about forensic tracking. However, those who rely on Microsoft account services or cloud-based device authentication should avoid deGDID, as they'll lose access to important functionality. It's not suitable for managed business environments, shared family PCs, or users who regularly authenticate across multiple Microsoft services.
Bottom line: Is deGDID a practical privacy solution for most users?
deGDID offers a unique tool for individuals who prioritize device privacy over full Microsoft service compatibility. While it can block new GDID tracking on personal Windows systems, it does so with clear functional trade-offs. Anyone considering this tool should evaluate how much they depend on Microsoft cloud authentication before running the script. For most users, robust endpoint and antivirus protection combined with good privacy hygiene may be a more practical choice, but deGDID fills a niche for those needing to minimize persistent device identification at the cost of some cloud functionality.
