Win under Install composer failed?

Environment is win7+php7+apache2.4
I installed this article according to http://blog.csdn.net/wxqee/article/details/44983931.
environment variable is also written, error encountered while adding configuration information to Composer global profile Config.json

This seems to be an environmental variable, but I'm checking that there should be no problem.
