php composer.phar update does not work with Symfony install

windows symfony wamp composer-php

Command composer self-update will do the trick.
For example:

goto cmd and jump into your project folder if in case
c:\wamp\www\{yourprojectfolder}
as your project
Run this
cd c:\wamp\www\{yourprojectfolder}
Use this
composer self-update

windows symfony wamp composer-php

You should try this instead:

composer.phar update

Why would php be aware of your $PATH variable?

Plus, I think $PATH is only used by your shell when dealing with the first word of your command line.

windows symfony wamp composer-php

You should logout and then login or restart in order to changes in path becomes available.
