About MSIX App Attach
MSIX app attach is an application layering solution that allows you to dynamically attach apps from an MSIX package to a user session. The MSIX package system separates apps from the operating system, making it easier to build images for virtual machines. MSIX packages also give you greater control over which apps your users can access in their virtual machines. You can even separate apps from the master image and give them to users later.
