INF File Entry Values That Modify Device Properties before Windows Vista

The following are the INF file entry values that modify device properties on Windows Server 2003, Windows XP, and Windows 2000:

  • INF file entry values that set device properties that correspond to the system-defined device properties that are part of the unified device property model in Windows Vista and later versions of Windows.

  • INF AddReg directives and INF DelReg directives that set or delete system-defined registry entry values that correspond to the system-defined device properties that are part of the unified device property model in Windows Vista and later versions.

  • INF AddReg directives and INF DelReg directives that set or delete custom registry entry values that correspond to custom device properties.

For general information about the INF file sections that install device instances, device setup classes, device interface classes, and device interfaces, see the following topics:

INF File Entry Values That Correspond to System-Defined Device Properties

Some INF file entry values provide information that Windows uses to set the system-defined registry entry values that correspond to device instance properties and device interface properties. The following are a few examples of registry entry values that are supplied by such INF file entry values:

INF AddReg Directives and INF DelReg Directives That Modify System-Defined Device Properties

Many system-defined device properties have corresponding system-defined registry entry values. For device properties that have corresponding registry entry values, using an INF AddReg directive to add the corresponding registry entry value sets the corresponding device property. Similarly, using an INF DelReg directive to delete the corresponding registry entry value, also deletes the corresponding device property.

For example, the INF AddReg directive in the following "Abc_Device_Install.HW" section would set the DeviceCharacteristics registry entry value for a device instance:

[Abc_Device_Install.HW]
...
AddReg = Xxx_AddReg
...
[Xxx_AddReg]
...
[HKR,,DeviceCharacteristics,0x10001,0x00000001
] 

The DeviceCharacteristics registry entry value corresponds to the DEVPKEY_Device_Characteristics property in the unified device property model in Windows Vista and later versions of Windows.

INF AddReg Directives and INF DelReg Directives That Modify Custom Registry Entry Values

Windows manages the correspondence between system-defined registry entry values and system-defined device properties. However, Windows does not manage the correspondence between custom registry entry values and custom device properties. An INF AddReg directive or an INF DelReg directive that modifies a custom registry entry value does not affect the system-defined properties that Windows manages.

Custom device instance properties that are set as shown in the following example, can be retrieved by calling SetupDiGetCustomDeviceProperty.

[XxxDDInstall.HW]
...
AddReg = Xxx_AddReg
...
[Xxx_AddReg]
...
[HKR,,CustomPropertyName,0x10001,0x00000001
]
