Instant WordPress is a complete standalone, portable WordPress development environment. It turns any Windows machine into a WordPress development server. It will even run from a USB key.
Instant WordPress comes complete with it’s own built in Apache web server, PHP and MySQL installations that are started and stopped automatically.
Instant WordPress comes complete with a set of dummy WordPress posts and pages so that you do not have to create any data or posts to test themes and plugins.
Instant WordPress is self-configuring, so it should not conflict with any software already running on your machine.
Instant WordPress can be installed as many times as you wish and deleted by simply removing the folder that it is running from. Nothing is left on your machine.
