Guide

For the same default Wine with Ajay prefix

• Run "Export All Registry (HCUS + HLMS).bat" to export all registry data.
  This includes registries for all apps and games.

• To restore the registry in a new container, run:
  "Import All Registry (HCUS + HLMS).bat"

Note: This may work with other Wine prefixes but with limited support.
It’s recommended to use the Ajay prefix registry, as it also includes game save file locations.
