Unable to download the windows update using script for Windows 10 from standard user

It seems downloader.Download() is behaving differently for Administrator and Standard user, specially on Windows 10 because same script is working fine on Windows 8.1 for standard user.

As per my understanding it seems like some issue on Windows side, could anyone help me to provide workaround for same ?
