I am facing a similar issue. I set the registry as mentioned in the documentation https://github.com/maharmstone/btrfs#secureboot .

Note that I also set the following registry setting because the install option was missing from the file explorer . https://answers.microsoft.com/en-us/windows/forum/all/install-option-missing-from-the-context-menu-of/23524ad3-1687-4c2d-ba26-b249b4c4d8e9

Edition Windows 10 Enterprise
Version 21H2
Installed on ‎10/‎10/‎2022
OS build 19044.2130
Experience Windows Feature Experience Pack 120.2212.4180.0

Now after setting the above and selecting the install option I get:

"This file does not have an app associated with it for performing this action. Please install an app or, if one is already installed, create an association in the Default Apps Settings page."

Then trying the Powershell option similar to @Grigoriy0 I get "Installation failed".

I am trying this on a MS Surface 2 laptop for which I have Administrator Access to mount / access btrfs filesystems on an external hard drive

It looks like I made forward progress. Using rundll32 syssetup,SetupInfObjectInstallAction DefaultInstall 128 .\btrfs.inf and I was able to install. A notification popped up after install but disappeared quickly and I cannot view. I am going to try a reboot and see if I can access the btrfs filesystems.

Just to be clear, this is an ARM laptop, right?
