Yes it seems Samsung is not up to par with the driver updates. I have two failed installs, after the second one I ran SetupDiag here's the results:
Error: SetupDiag reports rollback failure found.
Last Phase = Finalize
Last Operation = Remove System Restore checkpoints
Error = 0xC1900101-0x30018
After looking up that error code with microsoft:
|0xC1900101 - 0x30018||Disconnect all peripheral devices that are connected to the system, except for the mouse, keyboard and display.|
Contact your hardware vendor to obtain updated device drivers.
Ensure that "Download and install updates (recommended)" is accepted at the start of the upgrade process.
So it seems Samsung isn't very good at updating it's drivers for these Qualcomm 8cx laptops. I can't even run Samsung Update on my ARM Galaxy Book S. Just buy from a manufacturer that supports it's products.
