How to Update Microsoft Teams Rooms with PowerShell | Upgrading MTRoW

Hello there! Three weeks ago, I took part of Get-CSLATAM Conference in Mexico City, and I needed to take many devices there, so I asked a colleague for demo equipment. The mini PC for Microsoft Teams Rooms was delivered to my house, and I noticed it was running one old version of Windows and Teams App, therefore, it couldn't display the new home screen design and there were no advance features.

 

As you might expected, I upgraded that MTRoW because I wanted to show attendees how to take advantage of Teams Rooms and how to set them up, but my colleague is a great guy and he sent me a new Mini PC in order to show you how to upgrade your Teams rooms. Thank you so much JM for giving me an idea about a new blog post and, sending me another PC, in case you are reading this blog post.

Do you prefer a video to a reading? Take a look at my TY video:

Today, I'll take you trough powershell and Teams App. First of all, you don't need to upgrade your Teams Rooms every time Microsoft releases a new app version because Microsoft store updates your system in maintenance hours, but it's essential learning how to manually upgrade your system app. 

Now, let's get started. Go to admin account, if you didn't set a password, it would be "sfb".

First, let's have a look at what version your Mini PC is running, and supported versions.

Upgrading Windows OS

I recommend you check out Microsoft Teams Rooms App version support to know the windows release compatibility for Microsoft Teams Rooms app, before updating it, read that post carefully, as of today the supported versions of Windows verified to support Teams rooms are as follows:

Now, in your system, hit Windows + R, type in "winver" and click on OK to verified what version your system is running.

As far as I know, Windows 10 IoT Enterprise will reach end of support on October, 2025, and the 22H2 will be the final version of windows 10, therefore, make sure that your system is running it. For example, my Mini PC is running 20H2 version, an unsupported one, so I need to install the updates. Also, check out the OS Build, an unsupported one 👉👈😓

In case you don't need to update the OS, just skip this section, and go to Updating Teams App Section.

Now, hit windows key, and type "check for updates" and select the first option. 

 

 

You may view many updates to be installed, so start installing them, scroll down to view optional updates, check them, and select download and install.

 

 

After installing the updates, restart your system. 

Note: You can update a windows PC through PowerShell, in the near future I'll set aside time to write about it.

Updating Teams App

Sign in to Skype account, press windows key five times and log into the admin account.

Note: Pressing Windows key five times helps you be signed in to Skype and admin accounts at the same time.

Go here and download the latest Teams App as of today, or go to Microsoft Site and download the latest Teams App by clicking on the underlined link.

Now, you can transfer the psi file to your MTR by setting the destination path, selecting the file and clicking on Upload button.

 

In case you don't know how to transfer the file, I recommend you take a look at How to Remotely Access and Control Microsoft Teams Rooms, a blog post I published, or you can download psi file directly to one USB flash drive.

Open run dialog box, Pressing Windows + R brings up it, type in "Powershell" and press Ctrl + Shift + Enter.

 

In case a user account control window was opened, click on "Yes" button.

 

Note: Did you hit enter and open PowerShell for users? Swich from it to PowerShell for admins, type in the following command and run it.

start-process powershell -verb runas

 

Type in the following command to know what Teams App version the system is running.

Get-AppxPackage -AllUsers *SkypeRoom*

My Mini PC is running 4.10.10.0 👀

 

Now, enter the following command:  

PowerShell -ExecutionPolicy Unrestricted "path to script"

Did you remember where the file is located? I uploaded it to C:/Users/Admin, so this is the path I need to enter in, check out my command.

PowerShell -ExecutionPolicy Unrestricted "C:\Users\Admin\MTR-Update-4.16.134.0.ps1"

If needed, you can even check the path on Windows.

Enter the command and hit enter.

After a couple of minutes, you will see the following:

Again, check Teams app version.

Finally, restart your Mini PC, and that's all!
