I've seen this on two machines now - once when performing a manual upgrade using the ISO and once via WSUS.

Both times, the installer gets to 73%, then stays there - indefinitely.

On the manual installer, I can just click Cancel and after a short while, the installer disappears and I'm back at the desktop. But when installing via WSUS, there is no cancel button. I wonder if it's safe to restart the computer, or will that completely bork Windows??

Is there a log file for the 1809 update that I can take a look at to figure out what's going wrong on these two PCs?

The setupact.log in the %windir%\Panther folder is what you want to review to see what may have happened during the install. There might also be a $Windows.~BT folder. If there is, look for the setupact.log there.

Given where you are in the install process, I'd guess there's a device driver or something along those lines that causing the delay.
