Downgrade Drush from 8-dev to 7 I installed Drush  with composer global require drush/drush:dev-master but it has some problems. I am using Xampp and Windows 8. 

How can I downgrade Drush from 8-dev to 7?
# Remove the current version of drush.
composer global remove drush/drush
# Install drush version 7.
composer global require drush/drush:7.*
