Deletes all instances of Microsoft's GDID and prevents minting of new ones

The provided repository contains research and practical guidance on Microsoft's Global Device Identifier (GDID), a server-assigned installation identifier used by Windows even with local accounts. The key tool, degdid.ps1, focuses on removing existing GDID state from local stores while continuously blocking the DeviceAdd path, aiming to prevent the minting of new GDIDs on supported Windows targets.

This process is not intended for general privacy or legal suppression but rather as a protective measure for specific environments. The tool is designed for unmanaged personal Windows installations with a single user profile, currently validated on Windows 11 version 25H2/build 26200.
