Windows 8.1 seamlessly integrates new device protocol API

In Microsoft's official Windows App Builder blog, Microsoft showed an "exciting" improvement in Windows 8.1. Benefiting from the support of several innovative device protocol APIs, Windows 8.1 opens up the possibility of accessing a large number of devices. Microsoft said that the most exciting improvement is that the Windows 8.1 preview release the valve for accessing huge amounts of equipment.
