2 days later, without clicking Update and Restart from the shutdown menu, it seems somehow the update has once again tried to install itself, even though I always clicked Restart not Update and Restart, so now I get the stupid 0xc000021a error again, and I don't wanna spend another 40 minutes using acronis if the error is gonna show up anyway in a few days, besides my latest stable acronis backup is from 4 days ago, and that's A LOT of time for a backup (it's why I do daily backups but they're unusable now), anyone have any idea how can I fix this? I tried chkdsk /r /f, sfc /scannow, dism /online /cleanup-image /restorehealth, startup repair, but nothing has worked so far, I can only boot using disable driver signature enforcement but that's not really a solution. I even tried sigverif, says it's all good
The funny thing is, 1803 was never installed, it's just a trap so that it can show me a blue screen again and when I boot with disable driver signature enforcement it says 1709 again...
