Install - Msix Powershell All Users

Remove-Item -Recurse -Force $tempFolder

Deploying MSIX applications via PowerShell is a clean and efficient process when the correct scope parameters are utilized. The Add-AppxPackage cmdlet, combined with the -AllUsers flag, provides a robust mechanism for system administrators to enforce application availability across a device without relying on per-user scripting.

By implementing the script provided in this paper, organizations can integrate MSIX deployment into their CI/CD pipelines, configuration management tools (like SCCM or Intune), or manual provisioning scripts with a high degree of reliability.

The standard cmdlet Add-AppxPackage does not have a dedicated -AllUsers parameter in older PowerShell versions, but it achieves the same result if you run the command provisioning the package. install msix powershell all users

To install for all users (current and future users), you must use the -RequiredContentGroupOnly or strictly specify the package path.

The Command:

Add-AppxPackage -Path "C:\Path\To\YourApp.msix"

Wait, how does that install for All Users? In modern Windows versions (1809+), simply running Add-AppxPackage as Administrator stages the package. However, to ensure it is provisioned (available for future users), you should use the Add-AppxProvisionedPackage cmdlet (see Method 2 below), which is the technically correct way for "All Users" deployment. Remove-Item -Recurse -Force $tempFolder

Import-Certificate -FilePath "$tempFolder\app.cer" -CertStoreLocation "Cert:\LocalMachine\Root"

Once installed, how do you confirm the package is available for all users?

For production environments, you should combine certificate trust checks, error handling, and logging. Below is a robust script template. Deploying MSIX applications via PowerShell is a clean

Solution: Run Import-Module DISM before the command, or use the full path:
