Warning: The Windows installer still writes some registry keys (like uninstall info). This method is "mostly portable" but not perfectly clean.
PyCharm Community Edition Portable is a portable version of the PyCharm Community Edition IDE. The Community Edition is a free, open-source version of PyCharm, which offers many of the same features as the Professional Edition, but with some limitations. The portable version allows users to run PyCharm directly from a USB drive or any other portable storage device, without the need for installation.
This configuration ensures that every setting—from syntax schemes to virtual environments—remains on the removable drive, leaving the host machine untouched.
