Microsoft is implementing new standards to enhance the reliability of USB connections, particularly for devices that comply with the Windows Hardware Compatibility Program (WHCP). All WHCP-compliant hardware with USB Type-C must use USB-IF-certified silicon, ensuring efficient charging and support for DisplayPort Alt-Mode for additional monitors. USB4 certification requires a maximum data speed of 40 Gbps, up to 15 W of power for accessories, support for dual 4K displays at 60 Hz, and compatibility with PCIe and Thunderbolt 3. Testing is conducted through Microsoft's Hardware Lab Kit (HLK), and certification is paused if issues arise during testing. This initiative aims to clarify USB Type-C port capabilities and improve consumer confidence in WHCP-certified devices.

Microsoft has introduced new regulations to standardize USB-C ports on Windows 11 laptops, ensuring that all ports provide essential functionalities: display support, PC charging support, and data transfer. The updated Windows Hardware Compatibility Program (WHCP) mandates that every USB-C port must adhere to a minimum standard of functionality, allowing users to connect external monitors, charge devices, and transfer data efficiently. Ports supporting USB 40Gbps will also be compatible with USB4 and Thunderbolt 3 peripherals. These requirements are effective with the release of Windows 11 24H2. While the regulations establish a baseline, variations in specifications such as supported displays, power delivery capacity, and data transfer speeds may still exist and should be detailed in laptop specifications.
