1. Introduction The Windows Registry is a hierarchical database used by Microsoft Windows to store low-level settings for the operating system and applications. While typically used for key-value pairs (strings, integers, binary blobs), it can also be leveraged to represent matrix structures (2D arrays) by employing systematic naming conventions, serialization techniques, or multi-key arrangements.
