MSIX app attach Summary Intro

MSIX app attach offers a new capability for delivering MSIX packages to a Windows Virtual Desktop environment. The best way to describe MSIX app attach is, “Its a vehicle of delivering applications dynamically to a desktop or remote session” You can now attach applications based on groups and requirements. This provides a slick on demand delivery capability also known as “Dynamic Application Delivery” I sometimes refer to the acronym “DAD”.

Native MSIX’s are installed for a user or all users. MSIX app attach attaches a VHD/VHDX/CIM which essentially a prepared expanded version of the MSIX ready for use. This removes the need to install the MSIX and rather completes the following two processes (1) notify the operating system that the package is available (Stage) and (2) making the app package available to the user (register).

If a user needs an application in session, it is now possible using MSIX app attach to deliver required MSIX applications on the fly.


To help you get started with MSIX app attach, I have put together a comprehensive list of resources to help you on your way.
