# === variant 1: use try/catch with ErrorAction stop -> use write-error to signal Intune failed execution
# example:
# try

# Write-Error -Message "Could not write regsitry value" -Category OperationStopped
# $exitCode = -1

# === variant 2: ErrorVariable and check error variable -> use write-error to signal Intune failed execution
# example:
# Start-Process ... -ErrorVariable err -ErrorAction SilentlyContinue
# if ($err)
# {
# Write-Error -Message "Could not write regsitry value" -Category OperationStopped
# $exitCode = -1
