registry

Event fields used to define metadata about Windows registry entries in a system. The registry is a hierarchical database that contains data that is critical for the operation of Windows and the applications and services that run on Windows. The data is structured in a tree format. Each node in the tree is called a key. Each key can contain both subkeys and data entries called values. Sometimes, the presence of a key is all the data that an application requires; other times, an application opens a key and uses the values associated with the key. A key can have any number of values, and the values can be in any form.

There are six root keys (HKCU, HKU, HKCR, HKLM, HKCC and HKPD) that store information related to currently looged on users, local accounts, performance, and even the current hardware profile. Root-key names represent Windows handles (H) to Keys (K).

string

Registry values are the lowest-level element in the registry. They appear in the right pane of the registry editor window. Each entry consists of the value name, its Data Types in the Registry (which defines the length and format of data that the entry can store), and a field known as the data of the registry value. These are also known as registry entries. This field contains the full path. This field contains the key value name without the full registry key path
