Turn on auto updates, and let the updates get stored in the user's Personalization Layer. If auto updates happen daily, this might be the most convenient approach. Note that whenever there is a major product update, you'll need to reinstall on the UEP by redeploying the layer to the desktop with the Reinstall the layer checkbox selected.
Turn off auto updates, and redeploy the layer for each update. This requires updating the layer whenever you want to push out new updates.

- Install apps from a share or an ISO versus downloading them to the desktop to keep layer size to a minimum.
- Turn off automatic updates for applications. If automatic updates are left on, the updates will be put into the personalization layer. -- If this happens, you can use the "reinstall" feature to take back control of the application, and clearing the personalization layer of these conflicts/updates. - When installing an application that requires being part of a domain, it is ok to add the installation machine to the domain. -- After installing the application, remove the installation machine from the domain. -- Clean up the left over computer object in active directory - Installation machines can be added to View pools. Remember to remove them before finalizing the layer. This will prevent View certificate information from being saved in the layer.
