No user input required. | Pro Tip: Install from a URL (without downloading manually) $url = "https://cdn.example.com/app.msix" $out = "$env:TEMP\app.msix" Invoke-WebRequest -Uri $url -OutFile $out Add-AppxPackage -Path $out Remove-Item $out MSIX vs EXE/MSI Silent Install | Feature | MSIX | EXE / MSI | |---------|------|-----------| | Standard silent flag | -Path (PowerShell) | /quiet or /S | | User context | Works per-user or machine | Usually machine only | | Cleanup after uninstall | Fully containerized | Often leaves leftovers | Final Takeaway MSIX silent install is trivial – one PowerShell command. The real work is managing certificates, dependencies, and user vs. machine scope.
