## Description

Runs `Update-OSDeployCoreESD`, `Update-OSDeployCoreOS`, and `Update-OSDeployCoreDrivers` in a single call to refresh all local OSDeployCore assets.

Update-OSDeployCore [-Force] [-WhatIf] [-Confirm]
```

| Parameter  | Type     | Required | Description                                                                                                                            |

| `-WhatIf`  | `Switch` | No       | Shows what each sub-function would do without performing any downloads.                                                                |
