Step #6: MSIX App Attach
The next step is to configure MSIX App Attach images.
An MSIX App Attach Image is an expanded container, such as a vhd, vhdx, or cim file, that contains an extracted version of the MSIX packages. An image can contain one or more MSIX packages. The MSIX App Attach images are mounted to the session hosts in the host pool and the applications made available to users who sign in to the session hosts.
