I trying to install last version (5.6) of Laravel project but after install that, It was not version 5.6 but it is 5.5.32 !!!

I installed composer on my windows 10 and I did run composer global require "laravel/installer" and composer create-project --prefer-dist laravel/laravel blog according to https://laravel.com/docs/5.6/installation
