Now, let's look at the subkeys and values of the Windows 95 Registry. Registry subkeys are containers for Registry values or other subkeys. The subkeys break up the six main keys into logical groups. Each key has a set of default subkeys, but most systems have additional subkeys depending on the user or applications that are on the machine. The last levels in the Registry tree structure are values.
Values contain the actual configuration information used by the system.
The Registry values are similar to the text values used in the Windows 3.1 .INI files. However, Registry values are not limited to being just text strings, they can have different data types. Only one value is allowed per entry. It is displayed in hexadecimal format when using the Registry Editor. Hardware component information is typically stored in the raw binary format.
