1803 screw up my system to where it wouldn't recognize my GPU or detect my gsync monitor.
Quickly reverted back which magically detects all my hardware and left Microsoft a message I hope somebody reads and then hangs their head in shame. I've never had problems with a windows update before let alone anything as absurd as what occurred after I installed that garbage.
My sound card was not recognizable and I uninstalled driver and couldn;t install new one before I boot system without sound card installed and remove all traces from PC and install again. I thought update from 1709 to 1803 will be finished on that.
Next morning, 12h later new huge Cumulative Update waited me, and my PC become not usable even during download that update after download finished. I restarted PC and couldn't boot him any more. 20h I didn't have PC, until I tried several options after 2-3 OS reinstall. Lucky for me mobo BIOS back SSD on fabric default for 3 seconds and I didn't had problem with that part.
Now Cumulative Update shown on some pictures is hidden with tools and that's it.
