Spindle Document Capture hides drivers beginning with WIA. WIA stands for Windows Image Acquisition. Quoting from Wikipedia, WIA is a proprietary Microsoft driver model and application programming interface (API) for Microsoft Windows Me and later Windows operating systems that enables graphics software to communicate with imaging hardware such as scanners, digital cameras and Digital Video-equipment.
Spindle Document Capture hides WIA drivers as the API for TWAIN allows for better control over the scanner interface. To display WIA driver-enabled devices in the Pending Tray and other areas, a registry key needs to be modified.
