1. Visit the official JetBrains website. You can find PyCharm at this URL: https://www.jetbrains.com/pycharm/download/

2. On the download page, you’ll see two versions of PyCharm. PyCharm Professional is a paid version that offers more features like advanced support for web and scientific development. PyCharm Community is free and is great for pure Python development.

3. Depending on your needs, click the “Download” button under either PyCharm Professional or PyCharm Community.

4. The website should automatically recognize that you are on a Windows computer and give you the correct version for download. If not, make sure to select “Windows” in the platform selection.

5. Once the .exe file is downloaded, double click on it to run the installer. Follow the prompts and choose your preferences for installation.

Remember, you need to have a version of Python already installed on your computer to use PyCharm. You can download Python from the official website: https://www.python.org/downloads/
