Microsoft Pressures OEMs to Fix USB-C Warnings in Windows 11

Microsoft is urging original equipment manufacturers to correct hardware configurations that block USB-C troubleshooting alerts in Windows 11. The company’s guidance comes as part of a broader push—Microsoft pressures OEMs to fix recurring issues that prevent users from receiving vital notifications about slow charging, unsupported accessories, and faulty connections.

Although Windows 11 supports these alerts natively, Microsoft pressures OEMs to fix implementation flaws stemming from misconfigured Advanced Configuration and Power Interface (ACPI) descriptors. These errors include misidentified ports, missing ACPI methods, and confusion between internal and external connections, which can suppress alerts.

To address the problem, Microsoft recommends OEMs use the Windows Hardware Lab Kit to validate USB descriptors and test across various charging scenarios. The company also advises applying USB-C data transfer restrictions only to external ports and offering users manual control.

Microsoft is calling on partners to align with the Windows Hardware Compatibility Program to ensure a consistent user experience.
