2020-04-24T10:53:37+00:00 Installed KB4549951 on 16 April. All appeared fine at first.
Booted up my Dell E6640 on 23 April. Network icon showed airplane mode and there was immediate disruption on the (wired) network. Tried to toggle airplane mode to change icon back to correct ethernet icon, but all setting screens relating to network settings simply froze on launch. Unable to change any network settings. Ran sfc /scannow which found and corrected corrupt system files but this failed to cure the problem even after several reboots. Finally uninstalled KB4549951, rebooted and immediately everything was completely back to normal with correct network icon in notification area and network working fine.
Suspect network symptom of my problem with KB4549951 was broadcast storms knocking other devices off the network.

2020-04-24T07:21:26+00:00 Can you guys get your heads together ? All these updates to windows 10 since January has ruined my HP Pavilion gaming laptop. I spend more time waiting to get into windows from hello login screen ! Three times these updates have crashed my system to the point i have had to reset the machine using a flash drive. Only to recieve another update ! And my system failures start all over again. I have been a windows user since windows 95 platform i have to say windows 10 is THE WORST YOU MADE. I JUST WANT SIMPLICITY BACK!! I dont want all your updates yet i am forced to take them in windows 10. I read up to find ways to fix my laptop after every update and am horrified to see that microsoft claims to not know of the issues we are reporting. I mean seriously. Why do i have to sit in front of a laptop that forces updates and spending more time rectifying issues such as 100% Disk usage and or 100% memory usage. And having to do research online to fix the issue. I am afraid to shut down my system these days because another dreaded update. Once again i have sat here for nearly two hours just trying to log in after my system forced an accumalative update!!!! And having to use a flash drive yet again for the fourth time to reset my windows OS. Losing yet again all my files. Why should we have to keep fighting to use our systems ? Only to have them ruined by another update. Spending more time in 2 months trying to get on my system fixing my system than i am able to enjoy using my system! Frustrated in Michigan.
Amen
Not to mention all the devices and programs lost in the shuffle !
I miss just double clicking and downloading ...

2020-04-24T01:55:00+00:00 What a mess ! Since yesterday night I can't boot normally, in Safe Mode, or any other fashion. All files in Documents Folder have vanished. I tried to troubleshoot this major problem and nothing works. Sorry, but I'm so frustrated about this. To summarize, Windows 10 won't load. I get that Critical … error code. None of the options along Safe Mode are working, except for Prompt Mode. Repair Windows is not working. tried reverting to the last stable mode and it did nothing. I tried uninstalling the last update and it didn't do noting. The Asus recovery partition is empty. I just don't know what to do from there.
