This is a powerful script and you may get a pop up telling you that it's slowing down IE and that it may make your system become unresponsive. If this happens you can decide to continue if you choose, when we first tested it it gave us the pop up twice, and we ran it all the way out and the script worked great. You may choose to reboot prior to using this tool if the pop up message worries you or use a smaller list of data.
