Portable_XH is a portable CMSimple_XH distribution for Windows that is meant to run on your local machine without the need to have a webserver with PHP installed. It requires no installation, runs under a guest account and even from an USB storage medium. It doesn't allow access from other computers, particularly from the internet.
Portable_XH is the perfect solution to have a demo of CMSimple_XH at hand, or to portably prepare a website without uploading it to some webspace in the first place.
However, it is not meant to replace a local development environment. If you need this, you should look for XAMPP or any other of the major distributions.
As this distribution is an aggregation of different pieces of software, the folders contain independent software which is licensed separately as such. However, all of these licenses are OSI approved open source licenses.
For those looking ahead, there is also a release candidate with CMSimple_XH 1.7.1 and PHP 7.2.0RC4:
