What is MSIX?

Highlights

Package existing Windows apps. Use the MSIX Packaging Tool to create an MSIX package for any Windows app, old or new. The MSIX packaging tool streamlines the packaging experience, offering an interactive user interface or command line to convert and package Windows apps.
Install MSIX app packages. Use App Installer to install or update any MSIX app package that is locally available or on any content distribution network.
Apply run time fixes to packaged apps. The Package Support Framework is an open source kit that helps you apply fixes to your existing desktop app when you don't have access to the source code, so that it can run in an MSIX container.
Use MSIX anywhere. With the open source MSIX SDK, MSIX packages are more versatile, and platform independent. The SDK provides all of the APIs needed to verify, validate, and unpack an app package on any platform, including Windows 10 and non-Windows 10 platforms.

Benefits of app containers

Apps that are packaged using MSIX can be configured to run in a lightweight app container. The app's process, and its child processes, run inside the container, and are isolated using file system and registry virtualization. For more info, see MSIX AppContainer apps.

All AppContainer apps can read the global registry. An AppContainer app writes to its own virtual registry and application data folder, and that data is deleted when the app is uninstalled or reset. Other apps don't have access to the virtual registry or virtual file system of an AppContainer app.

如果是给所有用户安装的话，可以用everything搜出来app的位置。然后可以直接打开对应到路径
