What Uninstalling the App Does NOT Remove

Uninstalling Comfy Desktop only removes the launcher app itself. The following data is not removed and must be deleted manually if you want a complete cleanup:
The directories listed above contain your personal ComfyUI data (models, outputs, settings, and installations). They are not Comfy Desktop application files. Deleting them will permanently remove your data.
To fully remove everything:
  1. Delete the app data folder: %APPDATA%\Comfy Desktop
  2. Delete individual installations from within the app, or manually delete %LOCALAPPDATA%\Comfy-Desktop\ComfyUI-Installs (or %USERPROFILE%\ComfyUI-Installs if that is where they were created). Also delete any custom installation directories you configured
  3. Delete the shared model library at %LOCALAPPDATA%\Comfy-Desktop\ComfyUI-Shared (or %USERPROFILE%\ComfyUI-Shared) only if you no longer need these files
