This is just a "heads up" to those already on Windows 10 version 1903. Just got an "out of band" update KB4505903 on one of my Windows 10 Pro x64 machines. Upon completion of the install and logging back into the system, I was greeted with this screenshot. I've never seen anything like this appear in all the years having worked on and maintaining systems. NOTHING on the desktop was readable, just garbled code for icon names. The system control panel and file names were also showing this weird code.
It appears windows updates now works on a different set of functions, one of which is usocoreworker.exe . A second restart had the information in the below screenshot when the system fully booted. The extra reboot also CLEARED whatever the cause was and the system returned to normal.
If anyone out there sees this behavior with this out of band update, please, post as much information as possible here. I am opening a case with Microsoft into this possibly being a bug in Windows updates and its processes.
Update: Downloaded the AMD A8-7410 R5 driver package and installed on the machine with this update issue. Norton played well as did W10 1903. Looked at the event manager once again for the 27th, still can't see anything there of value which would lead me to a possible cause. In all, my opinion is this update still has some work to do before getting it right although this event may just be isolated to this machine. I will install on my AMD gaming rig tomorrow as it also has an AMD GPU as well as my Octacore AMD rig and see whether the issue reappears.
Microsoft pulled the update last Thursday, per their article on Ask Woody as others mentioned. I got the update via WU just yesterday, Saturday after finding there was an out of band update available and it was re-released, having not see it offered prior since I am on Pro and delay updates until manually checking. The update may STILL have an unknown issue as released thus I am diving into what others may or may not be seeing as a comparison. I've ONLY installed the update on one machine to see if it would hold any issues which is subsequently indeed did. NONE of the known issues in the update notes are applicable to the machine I used. The only hardware I am looking at is the AMD R5 graphics yet the system event isn't showing any issues with that.
Thanks for the feedback gents. The video drivers didn't seem to be an issue as I cannot find anything in the event viewer suggestive of that being the case. Holding my breath, the issue I posted about in private boards hasn't reappeared in a few days so I'm hoping something was updated in the background and corrected it. Sunil was given my sysdiag data for the team to review, knowing that takes time I hope to hear something regarding that soon. There was a fault bucket code in one of the screenshots I posted to, maybe that will send things in the right direction for the team to say what the issue was. The machine affected by this current issue appears to be ok now as well. Still monitoring things since my thoughts lean toward a MS installer being the issue.
For some time now when I get an update from Windows Update it then reboots and the screen comes up with a purple overall tinge. Doing a restart fixes it.
I do have the latest driver (AMD Radeon HD 7400 Series) for my addon video card but it's old and pre-Widows 10 although I read from Windows that it is supposed to download the latest update.
