If you haven’t already, create a notebook config file by running
jupyter notebook --generate-config
Then, edit the file jupyter_notebook_config.py found in the .jupyter folder of your home directory.
You need to change the line # c.NotebookApp.browser="" to c.NotebookApp.browser="C:/path/to/your/chrome.exe %s"
On windows 10, Chrome should be located C:/Program Files (x86)/Google/Chrome/Application/chrome.exe but check on your system to be sure.
