This is pertaining to a known issue with Teams app ver 5.3.11 running on Crestron UC-Engines.
The symptoms would include the touch panel being blank, and not registering any button presses except for around the perimeter of the screen.
A Quick fix is to hard set the video output to 1080p in Windows display options, and to make sure your display is also configured for 1080p.
The current workaround directly from Teams is the following:
1.Tap Win key 5 times to login as an Admin
2. Download the script DisableCopilotForMTR.ps1
2. Right-click the file, select "properties" then go to the "security" section, check the box to unblock the file.
3. Run the script on an impacted machine.
The script must be run while the Skype user is signed in.
The script must be run as an administrator, from an elevated prompt.
Here's the script: (Please copy/past to a text file and save as “DisableCopilotForMTR.ps1”)
$RelativeKeyPath = "\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\SystemAppData\Microsoft.MicrosoftOfficeHub_8wekyb3d8bbwe\WebViewHostStartupId"
$SkypeUser = Get-WmiObject Win32_UserAccount |? {$_.Name -eq "Skype"}
if ($SkypeUser -eq $null) {
Write-Host "No Skype user on this system. Cannot proceed."
Exit
}
$SkypeRegBase = "Registry::HKEY_USERS\{0}" -f $SkypeUser.SID
if (!(Test-Path $SkypeRegBase)) {
Write-Host "The Skype user registry path does not exist."
Write-Host "Please make sure the Skype user is currently signed in."
Exit
}
if (!(Test-Path ($SkypeRegBase + $RelativeKeyPath))) {
Write-Host "The Copilot registry path does not exist."
Write-Host "This system is not impacted by the problem this script is intended to mitigate."
Exit
}
try {
Set-ItemProperty ($SkypeRegBase + $RelativeKeyPath) -Name State -Value 1 -Force -ErrorAction Stop
} catch {
Write-Host "There was an error setting the registry value."
Write-Host "Please make sure you are running this script from an elevated administrator prompt."
Exit
}
Write-Host "Registry value set to disable Copilot for the Skype user."
