cavuman1 - thanks for that I saw it today. The problem that I think I have, is that I think I have older faulty Version 1909 files stuck in my system that it is trying to use to update the PC and I think I need to get rid of these files and start again, I believe this is possible.
My laptop is on V 1903 and the printers work ok but for some reason when I undo the latest update on the PC, not sure which version it is, I finish up with V 1803 or V 1809 depending on where you look in Settings!!!
I suspect it is trying to install a faulty 1909 but it may need 1903 first for everything to work, I'm not sure it will let me install KB4535996 and KB45375572 directly at the moment. I am not sure how I can install V1903 as I would like to go there first ,as this works on the laptop.
