Is Python Installed on Windows by Default?

No, Python is not installed on Windows by default. Here, we will explore the installation process, the reasons behind it, and the availability of different Python distributions on Windows.

The Default State of Python on Windows

Unlike on most Unix systems and services, where Python is usually pre-installed, Windows does not include a system-supported installation of Python. To make Python available, the CPython team has been providing precompiled Windows installer MSI packages with every release for many years.

Checking and Installing Python on Windows

To check if Python is installed on your Windows system, you can try running the command python --version in the command prompt. If Python is not installed, you will need to download it from the Python official website. After downloading, you can add Python to your environment variables to ensure that it is accessible system-wide.

On Windows 10, what is installed is a stub that directs you to the Windows store to install Python.

Security Considerations

It’s worth noting that Python is not preloaded on most Windows-based computers and other operating systems in general. A bare-bones installation does not include Python, which can be a security feature. Without Python, a hacker would not have the necessary runtime to execute dangerous scripts, as these scripts are typically just plain text. You can download and install Python from the Python site or the Microsoft Store.

Free Python Distributions for Windows

For those looking for alternative Python distributions, you have options such as ActivePython or Intel Python. These distributions often come with additional tools and libraries, making them more suitable for specific development needs.

Future Developments

Microsoft has announced plans to provide a link to install Python with Windows in the future. However, this does not mean that Python will be pre-installed. Instead, users will be directed to download and install Python from an external source. This approach ensures that users have the flexibility to choose the exact version and distribution that suits their needs.

Conclusion

While Python is not installed on Windows by default, the process of installing it is straightforward. With precompiled MSI packages and a wealth of free distributions available, you can easily set up Python on your Windows system. Whether you need it for development, data analysis, or scripting, Python is a powerful and easy-to-learn language that has a broad range of applications.
