I know what it does. Nice app, but it's redundant. To use this you have to have it installed on a running windows system. Meaning, you have already booted your system at least once with stock Windows. Gotcha. Device noted... This isn't a problem with NLite. Everything can be removed before the OS is installed. I'm not saying the app is bad, but from a telemetry standpoint, you already gave them your data setting up the stock OS.
