Cameras To Redirect Custom RDP Property Does not Work

Thank you, this helped me no end! I have used your original commands and created a more complete PowerShell script that checks to see if you already have the change applied before applying.

# Change the alias variable below, for a Remote Desktop resource type use the CollectionAlias from...  Get-RDVirtualDesktopCollection | Select-Object CollectionName, CollectionAlias
$alias = "ENTER_YOUR_ALIAS_HERE"

# Define the registry key path
$registry_key_path = "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\CentralPublishedResources\PublishedFarms\$alias\RemoteDesktops\$alias"

# Define the existing registry value name
$existing_value_name = "RDPFileContents"

# Define the value to add
$value_to_add = "camerastoredirect:s:*`n"

# Define the value to check
$value_to_check = "camerastoredirect:s:*"

# Get the current value of the registry key
try {
    $current_value = Get-ItemProperty -Path $registry_key_path -Name $existing_value_name -ErrorAction Stop | Select-Object -ExpandProperty $existing_value_name
} catch {
    $current_value = ""
}

# Check if the value_to_add is already present in the current value
if ($current_value -match $value_to_check) {
    Write-Host "'$value_to_check' is already present in the registry value '$existing_value_name' in the key '$registry_key_path'."
} else {
    # Construct the full value
    $full_value = "$value_to_add $current_value"

    # Use PowerShell to set the registry value
    try {
        Set-ItemProperty -Path $registry_key_path -Name $existing_value_name -Value $full_value
        Write-Host "Successfully added '$value_to_add' to the registry value '$existing_value_name' in the key '$registry_key_path'."
    } catch {
        Write-Host "Error: $_"
    }

}
