Registry Editor displays data in two panes. The value entries in the right pane are associated with the selected key in the left pane.
A value entry has three parts: the data type of the value (which appears as an icon), the name of the value, and the value itself. A value entry cannot be larger than about 64K. The limit to total Registry size depends on available hard disk space.
The following table lists the data types currently used by the system.
Data type | Description |
| Binary data. Most hardware component information is stored as binary data, and can be displayed in Registry Editor in binary or hexadecimal format. For example, Int 13: 01. |
| A sequence of characters representing human-readable text. For example, BitsPerPixel: "8". |
