I am very sad to see that. By running the service as admin/LOCAL_SYSTEM the security issue is still present. Everything the service does can be done as non-admin user, and certainly it doesn’t require LOCAL_SYSTEM priviliges. I have demonstrated it six months ago: Multipass on Windows - permissions, privileges, etc
Not only have you not fixed this severe security issue that is trivial to fix, but you also mislead readers to believe the Windows version is secure.
