Microsoft UEFI Compliant System Driver

The Microsoft UEFI Compliant System driver helps Windows recognize and interact with the computer’s Unified Extensible Firmware Interface (UEFI), the firmware that initializes hardware before the operating system starts. This Microsoft system component is normally supplied through Windows rather than installed as a separate hardware utility. If its entry shows a warning in Device Manager, checking Windows updates and your PC manufacturer’s firmware guidance is a useful starting point.

Key Features

• UEFI system recognition: Identifies the firmware-related system device so Windows can associate it with the appropriate built-in driver.
• Windows firmware integration: Supports communication between the operating system and supported UEFI interfaces; available capabilities depend on the computer’s firmware and Windows version.
• Built-in driver maintenance: Uses Microsoft-provided components that are generally maintained through Windows servicing, reducing the need for standalone downloads.
• Support across Windows versions: The device may appear on UEFI-based computers running Windows 11, 10, 8, or 7. Driver availability and compatibility depend on the operating system edition, architecture, and hardware configuration.

How to Install

1. Check your Windows version and device status. Open Device Manager, expand System devices, and look for Microsoft UEFI Compliant System. Open its properties and note any error code before making changes.

1. Check Windows Update. Install applicable system updates and review optional driver updates where available. Restart if prompted, then check whether the device warning has cleared. Update availability varies by Windows version and support status.

1. Try the built-in driver search. Right-click the device in Device Manager, select Update driver, and choose the automatic search option. Windows may report that the best available driver is already installed.

1. Use a manual package only when verified. If you have downloaded a driver, confirm that it explicitly supports your hardware, Windows version, and system architecture. Extract it if necessary, choose Browse my computer for drivers, and select the folder containing the compatible driver files. Do not force an unrelated driver onto the device.

1. Restart and verify operation. Return to Device Manager and check the device status. If a warning remains, consult your computer manufacturer’s support resources for chipset or UEFI firmware guidance. A firmware update is separate from a Windows driver update; avoid changing UEFI or legacy boot settings merely to resolve a driver warning.
