Faced the same problem. This worked for me. Open CMD and Find the tasks using tasklist | findstr "pythonw" Try to kill the tasks using taskkill /pid "processid" /f (Processid is the id u got from tasklist) Switch off wifi and try to open anaconda navigator

I loaded Process Hacker software on Windows 10 and in this software, I search for pythons.exe process, right click and select Terminate. This software is freeware. I am trying to help those who don’t want to type dos command.

For those who killed the Python processes but the GUI still doesn't show, for me the .condarc file was missing in my user folder... so I created the .condarc file and left it blank, killed the python process, then relaunched and it worked.

My issue was after installing for the first time

[With images] The instructions Below works flawlessly in Windows 10.

  1. Run CMD (command prompt) with administrator privileges
  2. Run the following command,
tasklist | findstr "pythonw"
  1. Lastly, after identifying process ID run this command to kill the process,
taskkill /f /pid <PID NUMBER>

Happy Learning :):)

I got the same problem on windows 10, and all the previous answers and commands to taskkill didn't work and gave me the error "Access denied".

I found out that when you turn off your computer in windows 10, by default it doesn't really turn off but instead it hibernates, so it doesn't really "kill" all the tasks running.

Therefore my solution:

  1. Go to Windows Start Menu, select _Settings > System > Power & sleep > Additional power settings > Chose what the power button does.
  2. Under Power button settings, tap the setting bar, choose the option "Shut down".
  3. Click on "Change settings that are currently unavailable", and uncheck the "Turn on fast startup" box.
  4. Click on save changes.
  5. Now Restart your computer.

This will successfully kill all running tasks, including pythonw, and hopefully solve your problem.

We can use either of below options to resolve the issue.

1. tasklist | findstr "pythonw"
   tskill <pid>
2. Also we can End the task names 'Python' from Task Manager.

Now open the Anaconda Navigator again. It may take a while to open.

The following steps worked for me in windows. You can do the following.

  1. tasklist | findstr "pythonw" The PID of the processes will get displayed.

  2. taskkill /pid "PID" (without quotes) /f

This will successfully kill the Anaconda Navigator task.

I met the same problem a few days ago. I found the anaconda navigator will start a process called pythonw. So the following is my solution:

  1. open a cmd window;
  2. use command tasklist | findstr "pythonw" to find the pid of pythonw, like 37200;
  3. use command tskill 37200 to kill the process.

By the way, my OS is Windows.
