Initially also me I didn't found the program but I discover next that in windows is a bit hidden with the name of Python 3.x.x(Miniconda# x.x.x 64-bit).Here the image for an example how it looks like In the case of it isn't listed in the control panel use this linux method deleting also the hidden files: https://docs.conda.io/projects/conda/en/latest/user-guide/install/linux.html.

The proper way to fully uninstall conda (Anaconda / Miniconda):

1. Remove all conda-related files and directories using the Anaconda-Clean package

   conda activate your_conda_env_name
   conda install anaconda-clean
   anaconda-clean # add `--yes` to avoid being prompted to delete each one
   

2. Remove your entire conda directory

   rm -rf ~/miniconda3
   

3. Remove the line which adds the conda path to the PATH environment variable

   vi ~/.bashrc
   # -> Search for conda and delete the lines containing it
   # -> If you're not sure if the line belongs to conda, comment it instead of deleting it just to be safe
   source ~/.bashrc
   

4. Remove the backup folder created by the the Anaconda-Clean package NOTE: Think twice before doing this, because after that you won't be able to restore anything from your old conda installation!

   rm -rf ~/.anaconda_backup
