I tried many things, scannow, DISM, etc. but the secret was in Wayne_723's post and that was to skip the updates. I used the Media Creator to create a USB install and when it got to the point where it asked if I wanted to check for updates I declined. It successfully completed the install on two laptops.
Help with "Windows 10 installation has failed" at 73% on Windows 8.1 Pro
Every time I try to install Windows 10 through the Media tool I always stop at 73%. I tried to do it on a Clean Boot and it was the same. I also tried to remove the "read-only" and "system" attributes on the "$WINDOWS.~BT", but it doesn't let me change the "Read-Only" attribute on a file called boot.sdi and I don't know how to remove the "System" attribute.

2022-10-03T19:03:49+00:00 I noticed no network activity between the time that Windows completed downloading Windows 10 and the time it started trying top download updates. I was too busy looking at that to disconnect right away and disconnected before the Download Updates kicked in, but you would probably be safe disconnecting once it's done downloading Windows 10 and at any point after that until it tells you that it's downloading updates. Since the download updates process would take a while, even if you don't stop it the exact second it starts, you should be able to stop it well before it gets to download anything.
Doing that should get you past the 73% part all the way to 100% and you can stay disconnected until it actually boots up as Windows 10. There will be some intermediate things before it gets there when it says that it's looking for something, but those will time out and it won't hurt to stay disconnected.
When to stop it won't be a big issue, and it's nice to see a thread without any "it didn't work for me" posts.
