I actually burned an installation disk, but the info seemed a bit contradictory, and I was worried about bricking a perfectly functional setup.
I don’t understand your comments about the licensing info — as far as I can tell, I have what MS calls a “digital license” which is lodged in the UEFI/BIOS data, because I took the upgrade path from a licensed Windows 8 installation.
I did keep existing personal data—that was the option in between trying to keep apps and keeping nothing, and I used the media creation tool.
Did your install finish OK or do you still have the issue?
Internet is slow for me tonight because I'm - yep - downloading an update. You can control that on Home edition by clicking the network connection and setting it to "Metered Connection", so it will at least ask before it clobbers your bandwidth. And guess what - the update resets it, and you have to do it all over again. Lovely.
