Install Msix Powershell All Users Today

PowerShell offers two primary approaches, each suited to different scenarios.

Automated Deployment of MSIX Packages for All Users Using PowerShell

Below is a production-ready PowerShell script that installs an MSIX package for all users, including certificate trust setup. install msix powershell all users

# Requires elevated session # Parameters $MsixPath = "C:\Deployment\MyApp.msix" $CertPath = "C:\Deployment\MyApp.cer" Write-Host "Installing certificate..." -ForegroundColor Cyan $Cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2($CertPath) $Store = New-Object System.Security.Cryptography.X509Certificates.X509Store("TrustedPeople", "LocalMachine") $Store.Open("ReadWrite") $Store.Add($Cert) $Store.Close() Step 2: Provision the package for all users (future and current) Write-Host "Provisioning MSIX for all users..." -ForegroundColor Cyan Add-AppxProvisionedPackage -Online -FolderPath (Split-Path $MsixPath -Parent) -SkipLicense Step 3: Optional - Register for currently logged-in users Add-AppxPackage -Path $MsixPath -Register -AllUsers Write-Host "Deployment complete." -ForegroundColor Green

Removal is symmetric. To fully clean a machine-wide installation: PowerShell offers two primary approaches, each suited to

# 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 "

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.

The evolution of Windows application packaging has led to the widespread adoption of the MSIX format. Designed as a universal packaging solution, MSIX combines the best features of MSI, AppX, and ClickOnce, offering a reliable, secure, and containerized deployment mechanism. However, deploying an MSIX package to all users on a Windows system—rather than just the current user—introduces specific technical challenges. While a double-click installation typically defaults to a per-user scope, enterprise and shared computing environments require machine-wide or per-machine installation. PowerShell provides the most robust, scriptable, and repeatable method to achieve this. This essay explores the rationale, prerequisites, core PowerShell commands, practical examples, and common troubleshooting steps for installing an MSIX package for all users.
