After a recent system restore, I started seeing these errors repeatedly in Event Viewer. Any ideas how to fix/troubleshoot? I've tried sfc /scannow, dism /restorehealth, and various troubleshooters.

I've been having the exact same issue since about May 8th. I'm looking around for answers, but so far nothing has come up.

It started recently around in 2~3 month.

Did you guys abandon Windows?

You guys need to focus on your OS not the Azure.

Hi!

Kinda having the same issue here with my aunts computer via remote. Search and Taskbar functions not working but i'm also having trouble starting windows defender. So it seems we have the same problem but it's showing itself in different ways.
Logs shows problem with backgroundtaskhost.exe and searchapp.exe when starting a dcom server.

Some of the text below is in Swedish, but those parts are not important.

We really need a fix for this now! Repairing or reinstalling is not an option due to remote connection and low computer knoledge locally.

With regards
Fredrik Åkesson

So, it seems that my problem is fixed. But sadly im not at all sure what i did. But after serveral tests with different solutions i finaly tried "sfc /scannow" again. And this time it said that it found a problem and fixed it. After a reboot everything works fine. I dont know why sfc said everything was fine the other 10 tries, but at least it fixed the problem for me. Now we can only hope that the rest of you will have the same "luck!"

I seem to be getting the same error now i'm rolling back updates one at a time since it just started happening for us. One weird thing i noticed is that i moved one computer from a remote site to our HQ site and it started working on its own.

Update KB5015807 isn't on our computers so i couldn't try uninstalling that first to test.

I ended up finding that Cisco AMP for Endpoints Connector was installed on our machines, this was a legacy AV from an ealier time that apparently was only installed on US machines (they did not have these issues in the UK). Mixing that particular AV software plus KBs from KB5015807 onward (i think it was april/may - current) was causing the issue. The solution was uninstalling Cisco AMP since we were moved to a different AV software anyway. I was not able to determine a root cause other than 'old AV software Cisco AMP was blocking DCOM service.' I would start investigating by uninstalling any AV software on a test machine and see if the issue still occurs. I found the easier one to test was the search bar in File Explorer, which failed to start nearly 100% of the time, the other issues like the start button, taskbar and windows screen snip were intermitten
