Yeah, that's a smart move. Also, try temporarily disconnecting any non-essential USB devices before the upgrade, as those can sometimes cause that error.
This. I had the same problem with that exact error. For me, it turned out to be a driver conflict, and my File History backup worked perfectly to restore everything.
You could also try creating a full system image backup for extra peace of mind, just in case. Another option is to run the Windows Update Troubleshooter, as it can sometimes resolve that specific error.
