Install Msix Powershell All Users ✓
Every MSIX is signed. For all-users installation, the signing certificate must be trusted at the machine level, not just user level.
# Install certificate to Trusted Root store (machine-wide)
Import-Certificate -FilePath ".\yourApp.cer" -CertStoreLocation "Cert:\LocalMachine\Root"
If you skip this, you’ll get the dreaded: Deployment failed because the package's certificate is not trusted on the system.
Many admins get confused by the term "Provisioned." Here is the distinction: install msix powershell all users
| Command | Scope | When does the app appear? |
| --- | --- | --- |
| Add-AppxPackage | Current user only | Immediately for that user |
| Add-AppxProvisionedPackage | All users (machine) | After reboot or new user login |
When you use Add-AppxProvisionedPackage, the package is staged for the machine. The actual installation for each user happens during their first logon after provisioning. This is why you might not see the app in the Start Menu immediately for currently logged-in users until they sign out and back in. Every MSIX is signed
The system must allow script execution.
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
Get-AppxPackage -Name "*YourAppName*" -AllUsers
In the modern Windows ecosystem, MSIX is the future of application packaging. Designed as a successor to traditional MSI, App-V, and even ClickOnce, MSIX offers a clean, secure, and reliable installation experience. However, one of the most common pain points for IT administrators and power users is deployment scope. If you skip this, you’ll get the dreaded:
By default,双击 an MSIX package installs it for the current user only. But in enterprise environments—shared workstations, Remote Desktop Services (RDS), or Virtual Desktop Infrastructure (VDI)—you need the app available for everyone who logs into the machine.
This is where the PowerShell command comes in. In this article, we will break down exactly how to install MSIX for all users using PowerShell, covering prerequisites, command syntax, common pitfalls, and best practices.
