Teams Room System Updated Manual Upgrade Process (2021)

Teams Room System will usually update from the Microsoft Store. However, sometimes you will end up in a situation where you want to update one of them to a newer software version immediately. Microsoft has updated the methodology for doing these manual updates in 2021 and I have documented this new process below. In the new method, the process involves downloading a PowerShell script that will be updated for each version of Teams Room System software. You need to run the script from Windows using PowerShell on the Room System hardware. Sounds easy enough, but there is a couple of tricks to making it work, so I’ve documented the steps here to save you some hassle.

 

Step 1: Plug a keyboard into your Teams Room System (you need this for the next step).

 

Step 2: From the normal MTR home screen, press the Windows Key 5 times in a row on the keyboard (Yes, really! Easier than Up Up Down Down Left Right Left Right B A Start, I guess). This will open up the Windows Login window without signing out the current Skype account.

 

MTR Home Screen
Press the Windows Key 5 times from this screen

 

Note: Do not try and log into the Windows install using the regular method (via Settings > Windows Settings) as this process will log you out of the Skype account and into the Admin account. If you then try to run the script you will get a “The Skype user must be logged in for this script to work correctly” error:


You can see in Task Manager that only the Admin user is logged in in this case which makes the script fail:

For the install to work you need to have both users logged in and Task Manager should show this:



Step 3: Download the Install Script from Microsoft:

If you have direct internet access you could do this directly from your Teams Room System or you can download it on your PC and copy it across to the MTR:

https://go.microsoft.com/fwlink/?linkid=2151817


Note: If the download link ever changes you should be able to get it from the main docs pages here: https://docs.microsoft.com/en-us/microsoftteams/rooms/manual-update#step-1-download-the-offline-app-update-script 


Step 4: Open PowerShell as Administrator from the Start menu by searching for it, right clicking on the icon and selecting “Run As Administrator”:

 



Step 5: Run the Script with the following command line (but using the script name with the appropriate version number for your particular upgrade):


PowerShell -ExecutionPolicy Unrestricted "C:\Users\Admin\Downloads\MTR-Update-4.9.12.0.ps1"




At this point the script will run and show quite a lot of logging. Here is a full print out of the logs from a working installation:
