Windows 10: Errors persisting in windows 10 even after clean install. Help needed!

I opted out of Onedrive, Hell I out right removed it, upon first boot (powershell and app removal) removed it from explore.exe too via registry. it more of I want to see how long it will take for MS to fix it or attest list the service in admin>services cause the service was there in earlier tech builds but was removed from rtm for some reason

 

Just FYI disabling this service also breaks the Mail, Calendar and People apps. It will prevent you from adding new accounts (you'll get an 0x80070402 error), and also prevents them from syncing (you'll get an "account settings out of date" error).

If you don't use those apps then I guess it won't matter to you, but if you want to use them you'll need to set the Start value to 3 (manual) and reboot. You may also need to remove and re-add your account(s) in those apps.

 

Sounds like it belongs to OneDrive. Maybe disable that and the problem goes away?

Just noticed this has already been mentioned.

 

I've been getting "The Sync Host_Session1 service terminated unexpectedly" and it seems to be related to a problem I had when I upgraded to Windows 10. I've done a clean install, but fast user switching has never worked. I am always logged out when I switch so all my running apps are terminated. Every time I try to switch, the above message appears in the event log (I think this may be the only time I see the message).

So I'm wondering whether I get logged off because the service failed.

Does anyone have any more information about why the service fails?

Sorry if this is slightly off topic.

 

No one of those solutions work for me. Error still in event viewer

 

A combination of deleting the OneSync Service (I'd already uninstalled One Sync) and setting the named services' "Start" DWORD value to 3 in HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services (see screenshot) worked for me.

I'm using win10 Pro and these services are only listed as being valid for the Home version so god knows why they are present in Pro.

 

They seem to be required for the Mail, Calendar and People apps (maybe others) to function, for both login and sync. Those apps are present in all Windows 10 editions, as far as I know.

 

Was having a hell of a time with 100% disk activity and 90% CPU because of this ******* but... After removing it I did lose mail and calendar functionality as noted a few posts back. Unfortunately I removed it before then.

My question is, how to I restore/reinstall the service? I've verified APhostservice.dll is where it's supposed to be. I've downloaded an ISO and attempted a dism repair... No luck. The error message listed a few posts back isn't quite right. It's 0x80070424, and it's associated with trustedinstaller/windows update.

If I'm an idiot and missing something easy, feel free to call me out, but I honestly can't figure how to get the service installed an running short of a refresh, which seems like a really bad idea.

Appreciate any assistance you can render.

 

Seems no one wanted to take a swing at this... I figured a way around it for anyone who did delete the onesyncsvc as discussed earlier in this thread. I simply exported the registry folder from one of my machines that was still running a stock setup, ran the .reg file on my laptop and rebooted.

I did encounter another error when attempting to readd the account to mail. Received 'account already exists' but I was able to get into account settings via calendar and delete the account remnant in question. Rebooted and done. I've installed and verified the account as a means to verify the above procedure was valid.

I've attached the .reg folder from a clean pc. You can use it, or not, it's off a fresh install.

 

hi
may i know why is not OneSync Service listened in the service list services.msc ?

i can't find it even in process hacker , or process explorer
i can find it only with w10 task manager

by the way i have the same errors

 

Why is this listed as 'solved' I've read this post from stem to stern and all the remedies have only put off a few things. I'm getting the same errors and no matter if the Start in registry is set to 2 or 3 or 4 they all return after a few reboots. I too have been working on eliminating Event View errors and also am a W7 upgraded to W10. To me solved is when it doesn't happen anymore....just sayin.

 

I marked it solved as the error was fixed for me and never got it again.

 

Wish I could say that. I've tried each and every one. Even deleting the OneSync in CMD prompt which promptly created about 220 more errors so I had to use Macrium Reflect to go back and do a image restore. (had sys restore turned off grr) all those registry Start settings from 2 to 3 to 4 all did nothing when rebooting. Funny how it works for some and not others. I too have W10 Pro x64 one thing I do have that may be another issue is I use the Classic Shell that mimics W7 but have seen no Shell errors in Event Viewer. It just may be that another error I'm having could be triggering all those 'Session' errors. Tried to use the W10 .ISO to repair it and the dang thing said 'Your PC Can't Run Windows 10' when its already on there, now that's a new one.

Outside of the Event errors the thing does run snappy but from time to time get DCOM errors; thought I had that one put back in its hole but it keeps popping up from time to time and from what I hear and read DCOM is a gateway for malware. Once I got rid of all the DCOM errors the system really seemed to to into a different gear with all sorts of things working that didn't previously like for instance the Task Bar started responding to mouse clicks whereas it didn't and startup sounds just to name a few.

thanks rezpower for atleast getting back...it must be nice not having those aggravating errors.

 

hi
have you really solved ?
i continue to get error *Sad

 

I marked this thread to unsolved as others still have the problem persisting and may need help.
