The issue  ‘jupyter’ is not recognized as an internal or external command  is mainly due to no path or wrong path of jupyter in windows environment variables. In my case related files were available in  C:\ProgramData\Anaconda3\Scripts  and so i have added this path in Windows as shown below and then you can run from any path: One important thing: after that while running jupter notebook from any location may give DLL Error. You have to first give command  activate base  and then jupyter notebook.
