I've just install latest version of the PgAdmin4 for windows but I cannot set up a server.
Did you install pgAdmin4 and PostgreSQL from the same bundled installer? Was PostgreSQL already installed? Were you trying to upgrade it at the same time as upgrading PgAdmin4?
Path settled, port configuration settled however postgre is not shows services.msc,
I don't know what "path settled" means. But your image of services.msc is showing the wrong part of the alphabet to show 'PostgreSQL'.
