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

I set OneSyncSvc Start to 4 and it only gets rid of one message shown below. Seeing as the the message has 'Sync' in it and the Service also has Sync in it it kind of makes sense. The other messages don't have Sync in them.

Since the other messages have Session1 in them I also set OneSyncSvc_Session1 Start to 4 but that didn't do anything.

Only error 'fixed'
-----------------
The Sync Host_Session1 service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 10000 milliseconds: Restart the service.
-----------------

 

Had a look through the Services in my Registry and there are a few that end in Session1 that correspond exactly to the error messages. Probably disabling all of them would get rid of the messages.

 

for me disabling only OneSyncSvc fixed all 4 errors. But if you still have the others try disabling all of them in the same way.

Make sure you backup your registry first *Smile

 

I set Start back to 2 and the message still don't show up in my Event Log. Have a look at this task in Task Manager. Service Host: Unistack Service Group (4). It looks like the thing that starts up all the services with the errors. It's near the end of the Process List.

You might not have it because of the Reg change you made.

 

I think that errors are generated at shutdown not startup.

**** Definitely at shutdown. I can tell by the times on the error messages.

 

I just set the OneSyncSvc start to 2 the original value and now the problem is fixed.
No more errors. Maybe the hotfixed today fixed this!?

 

Didn't fix it for me.

 

Sorry, you are right. Error back for me again! It didn't happen after two restarts but now its back *Sad
OneSyncSvc start set to 4 again.

 

I wouldn't worry about the messages. They are generated at shutdown so they are not slowing up startup. I have one more error message of the same type for VMware Workstation. Of course if anyone's Anal they want a clean Event Log. *Wink

In fact I lost power for a couple of minutes and my computer turned off. When power came back and I rebooted I didn't have any of these error messages in my Event Log. The reason being the shutdown process never occurred to produce the error messages. More proof they are shutdown messages.

I suppose there could be a bug in the shutdown process.

 

Well... The reason I posted here was that I Was on the hunt for a solution to my slow startup. This morning I desided to do a complete reinstallation of w10. I now have a huge number of errors including the ones in OP, but the startup is lightening fast and so is the rest of the user experience so I leave it at that.
Don't know about the anal thing...pragmatic is what I am*Wink
Over and out

 

Ok, not sure if anyone is still having problems. I found a way to disable Onesyncsvc and its other components with a simple command line in Elevated Command prompt<administrative>. Deleting the service is not required, going into registry also not required.

Copy and past the following lines into Cmd prompt Press enter, restart and your done. Hope this helps

sc stop "OneSyncSvc"
sc config "OneSyncSvc" start= disabled

 

Personally, I would leave things alone. I remember disabling the services and then getting other strange Event Log messages.

 

You only need to disable the one. Ive been keeping track of my event logs everything seems fine.

Edit--
I had some Errors mostly because of upgrading from windows 7 and not doing a clean install,
One was a Microsoft mouse and keyboard software update but didnt update associated tasks properly.
Another for kaspersky kl1.dll antivirus i didn't even have installed but dll and registry's remained.
Other errors related to windows media center task scheduling and a couple other void tasks.

After working through them all i managed to eliminate all errors in event manager.

 

My understanding is doing the
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\OneSyncSvc]

Start=4 does same exact thing

https://support.microsoft.com/en-us/kb/165748
scroll down little bit and you see
Boot 0x0 =0
System 0x1 =1
Automatic 0X2 =2
Manual 0x3 =3
Disabled 0x4 =4





Either way I have had this issue from day one, and know what caused and when since day two. doing either or we will never know when this is fixed. but if you look at eventviewer alot dont like seeing error, this is usfull. Im gona give MS while to see if they fix it before. before my ocd about seeing error makes me disable it. seeing it the only remain error i get every day

 

Just disable it if you don't use it, I was just getting the error because i opted out of Onedrive in windows settings. I can confirm zero side effects from Disabling this service. I can also confirm the service Stays disabled. Confirmed errors gone, confirmed on confirmed.
