latest jupyter version that support windows 7

As of my last knowledge update in October 2023, Jupyter Notebook does not officially support Windows 7 due to the end of mainstream support for that operating system by Microsoft in January 2020. However, some earlier versions of Jupyter Notebook may still work on Windows 7. If you need to run Jupyter on Windows 7, you might consider using Python 3.7 or 3.8, as those versions are more likely to be compatible with the last releases of Jupyter that can function on Windows 7. Generally, you might want to install a version of Jupyter Notebook that was released around the same time as Python 3.7 or 3.8. For the latest developments and compatibility issues, it's always a good idea to refer to the official Jupyter documentation or their GitHub repository. Additionally, consider upgrading your operating system to a more recent version if possible, as this will ensure better support and security for your software.
