Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Windows supports a platform for installing system and device firmware updates via driver packages that are processed by using the UEFI UpdateCapsule function. This platform provides a consistent, reliable firmware update experience, and it improves the discoverability of important system firmware updates for end-users.

The UEFI firmware update platform is supported by the following operating system versions:. All systems that run Windows 10 for desktop editions should implement UEFI firmware updates by following the UpdateCapsule-based update process described in this section of the documentation. There are two types of firmware that can be serviced via Windows: system firmware and device firmware. System firmware is responsible for providing critical boot and runtime services to the system as a whole, and device firmware is associated with a particular device integrated into a system.

Such device firmware typically works together with a device driver, allowing the OS to expose the device to OS-level services and applications. Windows will use information provided by the platform to ensure that the update package only applies to appropriate systems. A firmware update package contains a binary file containing the system firmware image. After the firmware update package is on the end-user’s system, Windows will use the UEFI UpdateCapsule function to hand-off the firmware payload to the platform firmware for processing.

Deploying the update as a driver package allows the firmware update process to align with many existing deployment and servicing tools, and ensures simple update package authoring for hardware vendors. Although the firmware update is delivered as a driver package, it does not mean that the update is written as an actual driver.

The driver package will contain an INF file and a binary file containing the system or device firmware image. For the purposes of updating device firmware, the device firmware can be assigned to one of these two categories:. This device firmware can be updated using a device driver package using the same mechanism as system firmware.

A device firmware update is distributed as a firmware update package. After the firmware update package is on the end-user’s system, Windows will use the UEFI UpdateCapsule function to hand-off the device firmware payload to the platform firmware for processing. This process is identical to how Windows hands off system firmware update payload, and is discussed below.

It’s recommended that device firmware is updated using a discrete firmware update driver package. However, device firmware may also be updated with system firmware as part of a single firmware update driver package. UEFI should not be used to update peripheral devices. UEFI requires devices to be present during reboot to apply a firmware update which cannot be guaranteed with external, removable peripheral devices. This device firmware can be updated by the device driver during the normal Windows OS runtime.

Updating device firmware using normal Windows OS drivers isn’t covered by this paper. In order for a system to be compatible with the Windows firmware updating mechanism, it must meet the following requirements:. UpdateCapsule is used to pass the firmware update payload between Windows and the platform firmware. System firmware, and some classes of device firmware, must be updatable using this process.

Firmware code recognizes a firmware update payload passed to UpdateCapsule and initiates the update process. The implementation is owned by the partner. The Firmware Resource allows Windows to surface a device instance with a Hardware ID, which will be used to target the system or device firmware update to appropriate systems and devices. It also describes the current firmware version and provides status for previous updates. There exists a single entry for system firmware updates.

All devices with updateable firmware must have a resource specified in the ESRT, unless a device’s firmware is updated as part of a system firmware update.

First, mobilestartup. This library allows the user to charge their device while the device is in the boot environment or is perceived as being turned off. This library is run first to ensure that the device has enough power to fully boot. For more information about scenarios involving the battery charging application, see Battery charging in the boot environment.

Next, mobilestartup. These libraries determine whether the device should boot to flashing or device reset mode, or if the device should continue to the Update OS or Main OS.

If mobilestartup. Battery charging in the boot environment. Architecture of the UEFI battery charging application. This device firmware can be updated by the device driver during the normal Windows OS runtime. Updating device firmware using normal Windows OS drivers isn’t covered by this paper.

Community Bot 1. The only way I know of to possibly write to the partition is during the Windows install process, within the WinPE or Specialize pass.

JW are you able to double check this? I’m able to create a directory and copy a file into it on Win10 Perhaps you’re referring to the Recovery partition that houses the Windows Recovery Environment?

I’m able to mount mine, but it’s not GUI accessible. After some experimenting, I can cd into it, and transfer files via cli, but it remains GUI inaccessible. Trying to open it in Explorer warns I don’t have permission to access it, and selecting Continue loads a permission denied error even though I gave myself permissions via icacls.

The Security Tab is also missing from properties and greyed out in the drive context menu. JW I believe access to it requires admin privilege, and Explorer only runs with regular user privilege. Hence an elevated cmd can access it but not Explorer.

UEFI is a general framework for boot loaders based on a standard UEFI specification, which describes a standard environment and set of interfaces for platform firmware that allows operating systems to boot. These applications should not be accessible to the end-user. OEMs that choose to implement UEFI applications should make sure that they have a small a memory footprint as possible and do not impact boot time.
