It appears you would like to take a trip into the windows dark forest.

Complete removal of windows defender on retail OS is feasible if you can figure out how to elevate a prompt to trusted installer. Alternatively, if you run Windows Server, you can use Remove-WindowsFeature to get it gone for good.

I have a script that accomplishes this, but I hesitate to share it because I don't want some asshole at Microsoft to patch it.
