So Im not really paying attention to the Version numbers. I just let her rip when new one comes out and if I dont like it I roll back. Here I am been running 1803.......well since it was released. Updated just fine. So i replace my GPU (have second on the way) with a strix 2080Ti O11G. I upgraded 3Dmarks to get the Port Royal and get an error that I have to be on 1809 to run it. Im up half the night, made M$ remote in and they ditched me! Like chat window closes then the link they sent me to reconnect doesnt work. This Idiot firstly was trying to do it off of an unmounted ISO to which it got an error very time, meanwhile Im just making a USB stick on another machine. So It just would not go, second reboot and 42% I get a sysprep error. All faqs said to remove unnecessary software and unplug hardware. So im bare bones with nothing plugged in except mouse, even unplugged keyboard and same story. I simpy would not update. Pull new GPU and put in spare 1080, NADA. Switched to alternate BIOS, NADA. Tried everything under the sun and in the end the update does not like VROC. Plugged in spare NVMe SSD in to DIMM.2_1 and cloned VROC array to spare SSD, pulled 900P drives, booted to spare SSD, did update without a hiccup, then cloned it back to 900P VROC array and working fine now. What a PITA!
So if you cant get the update to go ( still had to force it ) and you aare running VROC then clone to another drive, update, then clone back.
