Aggregator host error

CountMike · Jun 7, 2023

I'm having almost everyday error with Aggregator host stopped working but don't see any effects and can't find what it's for or what it does. Some suggested that it might be malware but there is Aggregator.exefor which Winowssays it's a system file and can see it in task manager as working.

Run all suggested tests and AV scan without any changes.

According to those it is coming clean but still no explanation why it stops working by itself.

I think I may have party found the problem, its connected to Trusted installer and I know I have trouble with it. I already inquired about it but found no solution.

Are you having any problems with Windows? I stopped checking the Computer Reliability app unless I actually notice a problem. Way to many problems were being found even though I wasn't having any problems.

Actually, only real problem was with Trusted installer preventing me from installing Realtek sound UAD diver and now aggregator which it seems to be connected to it. Except for it cluttering Computer Reliability app, I can't find any problems related to it.
Other red marks I can account for because they were result of my experiments with OC and UEFI. Yesterday I performed In Place upgrade with last W11 ISO available just to have system files renovated but that didn't help. Other than annoyance, for nownothing I can detect.

Hi @DavyD, welcome to the forum.
I run and tried everything I could find about it but it never cleared and don't even know what's it all about.

I realise that this is an old thread. So Sorry.

I realise that this thread is an old thread. Sorry but I just wanted to see if the OP and any others get this problem still?
I am using All Windows Insider versions. Can, Dev, Beta, Release Preview and Public.
Only Can and Public do not show the aggregator host problem at first boot. The other three show the fail at first boot every time.
Of course aggregator host is a genuine Windows Microsoft background process app. If I check Task manager immediately after first boot aggregator host is running normally.
This problem, for me, started when Canary build was split from Development build. All the older versions Dev, beta, R.P. started this. But Canary did not. I have filed numerous Feedbacks in the Hub but got no answer.
Apologies for restarting and old thread.
Regards,
DavyD

It's happening to me on RTM version of windows. It seems to crash but then runs again. The only thing I've been playing around with on this machine is WiFi drivers but no Idea if this has anything to do with it.
