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.

  Learn more in the [Migrate from Legacy](/installation/desktop/usage/migrate) guide.

## 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

You can also check for and manage updates from the Settings panel:

### 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           | `%USERPROFILE%\ComfyUI-Installs` | Each ComfyUI installation you created (can also be deleted from within the app). Custom install paths are also not removed. |
| Shared models & outputs | `%USERPROFILE%\ComfyUI-Shared`   | Shared model library, input/output directories                                                                              |
| App settings & registry | `%APPDATA%\Comfy Desktop`        | Settings, installation records, logs                                                                                        |

<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 `%USERPROFILE%\ComfyUI-Installs`
3. **Delete the shared model library** at `%USERPROFILE%\ComfyUI-Shared` (only if you no longer need these files)
