Persistent Telemetry: Permanent Microsoft Windows Identifier

Discussions about consumer privacy in the Windows ecosystem have focused on optional diagnostic settings and telemetry controls. Recently, the Global Device Identifier (GDID), a permanent device-level token embedded in the Windows operating system, was revealed in a U.S. Department of Justice complaint related to a cybercriminal investigation. The GDID uniquely identifies a Windows installation and is used by Microsoft services. It is generated when a device is linked to a Microsoft account and resides in the Windows registry, being included in data sent to remote servers. There is no option to disable or delete the GDID, and attempts to do so can disrupt essential features. This has led privacy-conscious users to consider alternatives like Linux, which offers more control over data and does not require persistent identifiers. For Windows users, strategies to minimize data linked to the GDID include using local accounts, disabling optional diagnostics, and reviewing cloud app sync settings. Privacy advocates are calling for better user controls and opt-out mechanisms for hardware tracking tokens.

Windows 11 Secure Boot is a messy ride on older PCs, and even Microsoft can’t fix it

Microsoft held an OEM Secure Boot Office Hours event with manufacturers like Acer, Asus, Dell, and HP to discuss issues related to the Windows 11 Secure Boot 2023 certificate rollout. Many IT administrators left with unresolved concerns, particularly regarding Secure Boot certificate errors. Participants reported persistent problems, including failures of suggested solutions from official documentation to apply to their hardware configurations. Ed Tittel shared his experience with compliance issues related to CA-2023 certificates, noting that ASUS motherboards sometimes required Secure Boot to be disabled temporarily, while MSI models exhibited erratic behavior. ASRock systems needed manual key resets, and documentation was lacking. Devices from Dell, HP, and Lenovo performed better but still faced staggered rollouts and required multiple reboots for BIOS updates. Specific issues raised included HP's BitLocker recovery loop persisting even with the latest BIOS, challenges with legacy device support from HP, devices showing Secure Boot Status as Unknown, and failures in updating the KEK on HP EliteBooks. Some questions from IT administrators regarding Dell and HP went unanswered during the session. The experiences highlighted a trend of Secure Boot issues across multiple OEMs, not limited to a single vendor. IT administrators are advised to pilot updates on representative hardware, back up BitLocker recovery keys, and consult OEM-specific advisories. The unresolved issues reflect common challenges faced by users, indicating that problems with Secure Boot certificate deployments are widespread across various manufacturers.

Что такое троттлинг и как понять, что провайдер намеренно замедляет ваш трафик

Throttling is the intentional limitation of speed for specific types of traffic, services, protocols, devices, or users. It can occur due to various reasons, such as exceeding data caps, prioritization of certain services, load management during peak hours, or technical policies in networks. Users may experience speed drops that are selective to specific traffic types, indicating potential throttling, while universal slowdowns suggest network overload or outages. Speed tests measure connectivity to specific servers and may not reflect actual download speeds across different paths. Signs of potential throttling include isolated speed drops, consistent slowdowns at specific times, and discrepancies between speed tests and real-world performance. Initial checks should rule out home network issues, and practical diagnostics can help identify throttling by comparing speeds across different servers, types of downloads, and times of day. If throttling is confirmed and support does not resolve the issue, exploring alternative ISPs may be necessary.

Microsoft tests Copilot’s new PC insights feature in Windows 11

Microsoft is piloting a feature called “PC insights” in its Windows 11 Copilot app, allowing users to inquire about their computer's hardware specifications such as RAM, storage, GPU performance, processor usage, antivirus status, and battery health. The feature collects system data using Windows APIs with user consent, which can be granted as one-time or permanent access. Currently in the experimental phase, it is being rolled out in the United States and provides insights based on the device's current state. Microsoft has cautioned that the app may not always provide complete or accurate information and has reported that it consumes nearly 1GB of RAM while idle. “PC insights” serves as a troubleshooting tool to help identify performance issues without resolving them directly. Future updates may enhance its capabilities to suggest adjustments or implement configuration changes.

Microsoft Confirms Windows GDID Device Identifier That Cannot Be Disabled, Documented in FBI Case Filing

Microsoft has confirmed the existence of the Global Device Identifier (GDID), a unique identifier assigned to Windows installations, in a federal complaint against an alleged member of the Scattered Spider hacking group. The GDID is generated when a Windows system is set up with a Microsoft Account and remains active through various Windows updates. Disabling the GDID could disrupt Windows activation and access to Microsoft Store applications. The GDID is described as "a persistent, device-level identifier designed to uniquely identify an installation of a Windows operating system on a device." It is created during the provisioning of Windows with a Microsoft Account and is stored in the Windows registry under HKCUSOFTWAREMicrosoftIdentityCRLExtendedProperties. The GDID remains persistent through Windows updates but is not retained after a clean reinstall. A single user can possess multiple GDIDs linked through their account, OneDrive, and activation history. The FBI used the GDID to track Peter Stokes, an alleged member of the Scattered Spider group, across various VPN connections and proxy servers. The GDID was recorded visiting specific websites and was linked to Stokes's accounts on platforms like Snapchat and Facebook. Concerns have been raised regarding user privacy, as the GDID is assigned without user consent and cannot be disabled without compromising essential Windows features. Microsoft has not committed to providing user-facing controls or comprehensive documentation for everyday users regarding the GDID. Legal requests can compel Microsoft to disclose GDID activity data to law enforcement. The GDID is linked to the Microsoft Account rather than the device itself, meaning reinstalling the operating system does not sever this connection.

Windows 11 Has a Hidden Tracker – Here’s How to Limit It

Peter Stokes is involved in a breach with a luxury retailer, using tactics like VPNs and rotating IP addresses to hide his digital activity. The FBI discovered a Global Device Identifier (GDID) linked to his Windows installation, which is a persistent device-level identifier that uniquely identifies Windows installations. GDID remains unchanged through operating system updates but resets with a full reinstallation. Disabling GDID is not possible, as attempts to do so would disrupt Windows activation. Users can minimize data linked to GDID by using a local account, reducing diagnostic telemetry, disabling Activity history, and carefully managing reinstalls. VPNs do not prevent Microsoft from logging GDID, IP address, and URL data. Privacy researchers view GDID as a covert tracking mechanism, and Windows lacks user-facing options to reset this identifier, unlike Apple and Google.

You can’t fully disable Microsoft’s GDID Windows 11 tracker, but these settings limit what it captures

A 19-year-old named Peter Stokes was detained at Helsinki airport in April 2026 while traveling to Japan, carrying two 2TB hard drives. He was subject to an Interpol Red Notice and faced a federal complaint from U.S. prosecutors by July for his alleged involvement in the Scattered Spider hacking group, which breached a U.S. luxury jewelry retailer in May 2025, leading to a ransom demand. The Global Device Identifier (GDID), developed by Microsoft, is a persistent identifier that uniquely identifies a Windows installation on a device. It links online activities back to a single identity, which law enforcement can use to trace a device's owner. The GDID is generated when a user signs into Windows with a Microsoft Account and remains through updates but does not survive a clean reinstall. Stokes' use of the same Windows device allowed investigators to trace his activities through the GDID, which linked him to the hacking incident. Privacy advocates have raised concerns about the lack of consent for GDID assignment and the potential for surveillance.

Why most AI projects fail: It’s infrastructure and people

AI technology faces significant criticism for its low success rates in delivering business results, with studies indicating a 95% failure rate for enterprise AI solutions and only 9% of organizations in Europe, the Middle East, and Africa achieving measurable outcomes from AI initiatives. Four main shortcomings hinder the transition of AI prototypes to production: 1. Deployment Flexibility: Prototyping environments often lack the necessary flexibility for large-scale production deployment, particularly in regulated sectors. 2. Data Sovereignty: Production transitions can complicate data sovereignty at enterprise and regional levels. 3. Reliability: High availability is crucial for production environments, but vendor-managed platforms may not guarantee seamless upgrades or hardware swaps without downtime. 4. Disconnect in Tool Selection: Developers often choose tools for prototyping without considering production implications, leading to difficulties in scaling. The shortage of database administrators (DBAs) is exacerbated by the increasing use of AI tools, with 84% of developers utilizing them according to a 2025 survey. To address these challenges, Merrick suggests leveraging AI DBA agents to support human DBAs and improve database management efficiency. He emphasizes the need for both robust data infrastructure and enhanced operational support to improve the success rates of AI prototypes.
