How can I restart the PHP environment installed with Drush for Windows? I have installed Drush for Windows, works great, but it installs its own version of PHP in a subdir of the install directory.  I've increased the memory limit and execution times in that ini but how can I restart that PHP environment (if in fact that is even the correct PHP environment).  Short of restarting my machine (which is fine) just wondering what would be the way to do this?
Drush works using CLI. It means it is not dependent on web server you are using. "Restarting environment" simply does not apply, Command Line Interface PHP is started each time you call drush, and stops when drush finishes it's job, that's all.
