Install Msix Powershell All Users -

# List all provisioned packages Get-AppxProvisionedPackage -Online | Select DisplayName, Version Get-AppxProvisionedPackage -Online | Where-Object $_.DisplayName -eq "YourAppName" For a specific user's installed packages (run as that user) Get-AppxPackage -Name " YourAppName "

This cmdlet provisions the MSIX package for all users before they log in. When a new user signs in, Windows automatically stages and installs the application from the provisioned package. This is the gold standard for machine-wide deployment.

Automated Deployment of MSIX Packages for All Users Using PowerShell install msix powershell all users

# Remove provisioning so new users don't get it Get-AppxProvisionedPackage -Online | Where-Object $_.DisplayName -eq "YourAppName" | Remove-AppxProvisionedPackage -Online Get-AppxPackage -AllUsers -Name " YourAppName " | Remove-AppxPackage -AllUsers

The Add-AppxPackage cmdlet has a -AllUsers parameter. However, this is less effective for future users. It installs the package for all currently existing users but may not automatically provision it for users created later. Therefore, Add-AppxProvisionedPackage is generally superior.
