Microsoft is updating its Windows Hardware Compatibility Program (WHCP) for Windows 11 to standardize USB-C port functionality across devices. The new guidelines will ensure that all USB-C ports on certified Windows 11 devices support data transfer, charging, and display output. This initiative aims to eliminate confusion for users regarding port capabilities. Additionally, USB 40Gbps ports will be compatible with USB4 and Thunderbolt 3 peripherals, while USB 3.X ports may not match the performance of USB4. Microsoft will also require USB-IF certified silicon in PCs and will validate USB controllers with its own drivers to ensure seamless updates through Windows Update.
