When you first open the app, you'll see the **Welcome** screen where you can create your first installation.

<Tip>
  **Already using Legacy Desktop?** Comfy Desktop can automatically detect and migrate your existing installation. Your custom nodes, workflows, models, and settings are carried over — nothing is lost. The legacy installation is kept untouched as a backup.

## Updating Comfy Desktop

Comfy Desktop automatically checks for updates and lets you manage them in two ways.

## Quick Update

When an update is available, a **Desktop Update Ready** button appears at the top of the window:

Just click the ① <Icon icon="arrows-rotate" /> Desktop Update Ready button and Comfy Desktop will restart and install the update automatically.

## Manual Update via Settings

### 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:

| Data                    | Default Location                                | Description                                                                                                                                                                                    |
| ----------------------- | ----------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Installations           | `%LOCALAPPDATA%\Comfy-Desktop\ComfyUI-Installs` | Each ComfyUI installation you created (can also be deleted from within the app). Custom install paths are also not removed. Older installs may still live in `%USERPROFILE%\ComfyUI-Installs`. |
| Shared models & outputs | `%LOCALAPPDATA%\Comfy-Desktop\ComfyUI-Shared`   | Shared model library, input/output directories. Older installs may still use `%USERPROFILE%\ComfyUI-Shared`.                                                                                   |
| App settings & registry | `%APPDATA%\Comfy Desktop`                       | Settings and installation records                                                                                                                                                              |
| Logs                    | `%APPDATA%\Comfy Desktop\logs`                  | Desktop app logs (`app.log`)                                                                                                                                                                   |

<Warning>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.</Warning>

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
