Hello I'm wondering if someone uncovered what exactly are the paths and files or registry keys that are being changed when the user is changing the OS customizations in the first use during the installation procedure, when not selecting "Use Express Settings". Currenty I have an old HDD with one of the Win10 preview ISOs installed. But that doesn't help, I hoped I could do some kind of installation background diagnostic trace if possible. And I'm testing with VM now on Win7 with VirtualBox. And I can't see other than read/write events for the VDI file in Process Montitor running on the host machine, I'm not sure if the offset info could help me since I heard VDI files are less friendly to raw browsing. Or a program that can detect changes and point them out in a block of memory, like CheatEngine maybe? Or some remote debugging session, aren't at MS debugging their own OS, don't they have an ability to trace the whole PC via some serial link or something for pretty much anything including the installation process. The only other option is to go dig into the ISO directly and try to find where the installation part is, maybe some clues where that is located so it saves me some time?
