Hi rocksteady. We definitely tested this feature in our QA. It was also presented in beta but I didn't notice any feedback for this feature during beta version on this forum. To be sure, if there is any last change, I verified just now and it sill works in 21.3.2459 release.
Could you please run manually from your USB disk Rescue\aswPEBrowser.exe to verify if it works this way? Without rebooting to Rescue Disk, just from your standard Windows installation. If it does, when you reboot to Rescue Disk and start command line tool, what Windows version do you have?
And if you can see on your USB file Rescue\debug.log , could you please post it here? It's Chromium framework debug log, there might be some errors interesting for us.
Thank you.
