Windows uses setup information (INF) files to install the following components for a device:
One or more drivers that support the device.
Co-installers or class installers for the device.
Device-specific applications, which are installed by using a device installation application. These applications are first copied to the user's hard drive through a directive within the INF file. After the applications are copied, they can be launched by using a co-installer's finish-install wizard pages or finish-install actions).
You can use an INX file to automatically create an INF file. An INX file is an INF file that contains string variables that represent version information. The Build utility and the Stampinf tool replace the string variables in INX files with text strings that represent a specific hardware architecture or framework version. For more information about INX files, see Using INX Files to Create INF Files.
