Okay, then that requires reassessing from the start as your first post was simply about the interface looking different than you expected.
Did you try installing in ways recommended in 2025 for Windows 10 machines? My concern is you are already facing an uphill battle with trying to install things on this old system. On a newer system I would recommend installing JupyterLab Desktop as it supposed to be, “the quickest and easiest way to get started with Jupyter notebooks on your personal computer.” Failing that, I’d recommend trying to install the Anaconda Distribution. That will include Jupyter along with helpful things like Python that should work in conjunction with it.
Keep in mind that I was concerned about your ‘installed’ version looking old.
The problem with your post as it is that you have share very little information. Your comment, “It reports Python doesn’t respond correctly”, is rather vague. I would recommend seeing Getting good answers to your questions and looking at other posts with similar issues to get a better idea of what to try and what you may want to provide as you try things going forward.
