Click on the path click on edit then click on new then paste this C:\Program Files\PostgreSQL\13

your environment is set then go to cmd type psql -U Postgres then type the password boom done

The PATH contains directories, not the actual executable.

And programs are installed in c:\Program Files not c:\Windows\Program Files.

So you need to add c:\Program Files\PostgreSQL\9.6\bin to the path.
