This report is actually about a possible bug of the support assistant, not the graphics driver per se:
Right after the "Windows 10-x64 2018 October Update", it seems that the driver for my "Intel HD Graphics 620" was automatically downgraded to version "22.214.171.12401", although I am 100% sure that the latest version ("126.96.36.19973") was installed on my PC a couple of days before the Windows update.
It was obvious, because the screen was flickering while scrolling or when dragging windows around the screen and the overall experience was not smooth enough (like before).
So I started the "Intel Driver & Support Assistant" to check for new drivers, I saw the currently installed old version and also the message that there is NO update available for my PC, although the latest driver version is "188.8.131.5273".
In Device Manager it said "Windows has stopped this device because it has reported problems. (Code 43)".
Windows Update could not find any updates.
So I went ahead and manually downloaded & installed the latest driver available. Everything is smooth again. Yey!
