Process to update firmware on Microsoft Surface

What is the process to update the BIOS or firmware on a Microsoft Surface?

I have downloaded and installed several files but after these files are installed they simply create a C:\Program Files\SurfacePlatformInstaller folder that contains a "Drivers" and "Firmware" folder but there isn't an executable program or utility installed that will allow me to update the firmware or BIOS.

All of the Surfaces I am supporting are running Windows 10 Professional and have had all of the latest Windows updates installed.

There should be a .msi file in the downloaded folder.  This is a Microsoft Installer; right-click on it and select Install.

According to Microsoft, as long as Windows Updates is enabled, the system will update its own firmware without the need for manual updates.

"Two types of updates keep your Surface performing its best: Surface hardware updates (also known as firmware) and Windows software updates. Both types install automatically as they become available."

Here is the BIOS download link from Microsoft

Look down in the instructions and expand the install link.  It says follow the instructions in the included PDF file.

Ultimately there should be a file you run. That is how I update UEFI BIOS on my Lenovo machine.
