I use event viewer for quiet a bit at home, but haven't had issues with it.
I have noted only two issues with 1903... One was documented already, and that's the whole, "oh, you have a flash drive pluged up, well I dont know how to update anymore!" deal. Apparently even having secondary hard drives that are removable can also cause that glitch when trying to update to 1903.
My next issue is something that started happening somewhat recently. Every now and then, purely at random while on or during a cold boot, my rig forgets that it has a sound-card at all. It will end up listing only the Steam stuff that is part of SteamLink, it's as if the system totally forgot I have an onboard soundcard.
I noticed a similar bug with my mothers desktop over the course of the last year or so. Hers isn't a 1903 issue, but, purely at random, her install would forget theres a soundcard, and the only fix was to reboot.
Would be rather unusual for two systems to drop their soundcards, not be able to locate them, yet a reboot clears it typically. Never had a sound card fail before, so two rigs starting to have these issues is perplexing to me.
