UEFI System Firmware Update
OSD 21.7.11.1
OSD Module
Make sure that your OSD Module is at least version 21.7.11.1. Once you have that, you can use Get-MyBiosVersion to check your current BIOS version
Installing Firmware Drivers will require Admin Rights, and make sure you have your Bitlocker Keys backed up and that you suspend Bitlocker before any updates
UEFI Firmware Update Platform
Before going any further, its important to understand what the Windows Firmware update platform is. Enjoy the read and come back when you are up to speed
Device Manager
Taking the information from the Microsoft Windows UEFI firmware update platform link, you can see that (on Windows 10) the System Firmware is in Device Manager. Digging into the Details provides a value for the Firmware Resource ID
You can get this information from PowerShell using Get-CimInstance
Or use two new OSD Functions to provide this information
Microsoft Update Catalog
Finally you can take the System Firmware Resource (Guid) and run a search in Microsoft Update Catalog and you should be able to find the matching UEFI Firmware Updates for your system. Just select the newest one and download the CAB
MSCatalog Module
You can also query the Microsoft Update Catalog directly with the MSCatalog PowerShell Module written by Ryan Kowalewski
Get and Save SystemFirmwareUpdate
To make things easier for you, these two OSD Functions will help speed things along. Get-SystemFirmwareUpdate will return the newest UEFI System Firmware for your device and Save-SystemFirmwareUpdate will download the Update and expand the package
Install
Installation is quite simple. Simply right click on the firmware.inf and Install
Remember about suspending Bitlocker first!
Next Steps
Look for this to be added to OSDCloud soon after some more testing
