I believe that many computer users do not understand what keyboard key values ​​are. The editor will introduce the keyboard key values ​​to you. Keyboard key values ​​are how the system interprets registry settings. When we want to modify the registry, we modify the key values. The following is the most detailed Windows keyboard key value table. Understanding it in detail will be helpful to you.

A key is a point in the registry in Windows. The key value is located at the end of the registry structure chain, similar to the file system file, and contains the actual configuration information and data used when the current computer and application are opened. The key value contains several data types to adapt to the usage needs of different environments.

The key value item consists of three parts: key value name, data type and key value. Its format is: "key value name: data type: key value".

These key-value item data can be divided into the following three types:

First, string value (S)

In the Windows 98 registry, string values ​​are generally used to represent file descriptions, hardware identification and other information. A string value consists of letters and numbers, and its maximum length cannot be higher than 255 characters. A kind of key-value item data is formed through keys and key values, which is equivalent to the setting lines under each section in the Win.ini and Ssytem.ini files.

Second, binary value (B)

In the Windows registry, there is no length limit for binary values ​​and can be any number of bytes long. In the Registry Editor, binaries are displayed in hexadecimal format.

Third, DWORD value (D)

In the Windows 98 registry, the DWORD value is a 32-bit (double-byte long) value. In the Registry Editor, the system displays the DWORD value in hexadecimal format.
