Powershell All Users New! — Install Msix

To install an MSIX package for all users via PowerShell, you must "provision" it at the operating system level. Unlike Add-AppxPackage, which only installs for the current user, provisioning ensures the app is pre-installed for every existing user and automatically registered for any new users who sign in. Installation Command

Add-AppxPackage -Path "\\server\share\MyApp.msix" -Scope Machine -ErrorAction Stop

1. Administrator Privileges

All-users installation requires elevated rights. You must run PowerShell as Administrator. Without elevation, the command will fail with an access denied error.

App Installer: Ensure the "App Installer" tool is updated via the Microsoft Store, as it handles many underlying MSIX technologies.

: To uninstall the package so it no longer appears for new users:
