OneSyncSvc — что это за служба и как отключить? (Sync Host)

Приветствую. OneSyncSvc — служба/сервис для синхронизации почты, контактов, календаря и некоторых других пользовательских данных.

У некоторых пользователей появляется окошко — Прекращена работа программы OneSyncSvc:

В таком случае и правда можно попробовать отключить службу. Отображаемое название на русском — Синхронизация узла (англ Sync Host):

Отключение

Нет уверенности, но возможно отключение службы может вызвать проблемы в метро-приложениях, например почта.

При помощи реестра (инфа взята с форума Майкрософт):

1. Зажимаем Win + R.
2. Пишем команду regedit, нажимаем ОК.
3. Откроется редактор реестра, переходим по такому пути:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\OneSyncSvc

Вы должны попасть в папку OneSyncSvc, в которой будет параметр Start — нажмите по нему два раза, установите значение 4 (Отключено).

Второй способ попробовать отключить — через окно служб:

1. Зажимаем Win + R.
2. Пишем команду services.msc, нажимаем ОК.
3. Откроется список.
4. Находим службу, название может быть OneSyncSvc/Sync Host/Синхронизация узла, нажимаем два раза — в меню Тип запуска выбираем Отключена. Также нажимаем кнопку Остановить.

Пример на службе Windows Search:

Использование консоли

На одном сайте были найдены команды отключения/удаления. Последнее делать рекомендую только при созданной заранее точки восстановления. Команды необходимо использовать в командной строке, запустить можно так:

1. Правой кнопкой нажимаете по значку Пуск, выбираете пункт командная строка от администратора. Способ для Windows 10.
2. Через диспетчер задач — в левом верхнем углу нажимаете Файл > Запустить новую задачу > ставите галочку Создать задачу с правами администратора > указываете команду cmd.exe > нажимаете ОК.

Команда остановки и отключения службы:

sc stop «OneSyncSvc» & sc config «OneSyncSvc» start= disabled

Should I Disable Windows 10 OneSyncSvc Service?

The OneSyncSvc synchronizes your Microsoft Account, OneDrive, Windows Mail, Contacts, Calendar and various other Apps. Your Mail App and other Apps and services, which are dependent upon this functionality, will not work properly when this service is disabled or not running.

Since I don’t personally use any of these services or its related Apps I decided to disable it. To my bliss, browsing my Workgroup network with Windows Explorer is near instantaneous by comparison. In short, there are no more delays in opening networked folders.

How to Disable OneSyncSvc Service #

Again, assuming you don’t use or need any of the above related services or Apps and want to browse your networked computers faster give disabling the OneSyncSvc service a try. To disable OneSyncSvc click “Start” and type “regedit” then press “Enter” on your keyboard. Copy and paste the below address into the address bar at the top:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\OneSyncSvc

Locate and set the “Start” DWORD from the default value of “2” to “4“. A restart would be required to implement this change.

You would then want to “Favorite” this location within your Registry Editor in case you change your mind or run into issues. Then simply revert the Start DWORD back to “2” to enable the OneSyncSvc service and all its related functionality. Once again, a restart would be required to implement this change.

End of File #

I hope this article has helped increase the speed with which you browse your networked environment. I welcome your thoughts, questions or suggestions regarding this article.

Again, if you use any of the above mentioned services you would not want to disable the OneSyncSvc service.

Question

I am using the latest version of Windows Server 2016 with all updates installed. This is a very basic and clean install.

When the server manager pops up after booting it is giving me an error. (Service Stopped)

I have tried disabling it via the services.msc interface. When I change the startup method to something other than Automatic (Delayed) I am receiving a «Parameter is incorrect» message.

I have also tried disabling via the CMD prompt:

sc config OneSyncSnc_2e345 start = disabled

Does anyone else have this issue and what did you do about it?

All replies

I followed the suggestion to use: sc config «OneSyncSvc» start= disabled

However, doing so resulted in 3 new errors. I re-enabled the delayed start and the 3 new errors persisted, in addition to the OneSync error. Uggh.

The errors I have are:

Sync Host_xxxxx
Diagnostic Policy Service
User Access Logging Service
Distributed Transaction Coordinator

Researching those now.

I want to confirm with you that if your Sync Host service has been display with name “Sync Host_2e345”.

Please find Start registry entry and change its value to 4:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\OneSyncSvc_2e345

Note that: back up registry before any change, it would be helpful for restoration if there is any problem happens after the change.

In the registry editor I have the following entries:

I do not have OneSyncSvc_2e345

It appears the current START value for all three is 2 (decimal).

Start entry with value 2 means – Automatic, the service is loaded or started automatically.
Start entry with value 4 means — Disabled. Specifies that the service should not be started.

Please back up registry entry first — How to back up and restore the registry in Windows：
https://support.microsoft.com/en-us/help/322756/how-to-back-up-and-restore-the-registry-in-windows

then, please change the Start entry of each OneSyncSvc entry you had listed. Then, re-start the system and check the result.

That appears to have resolved the issue. I am no longer receiving warning messages on the Server Manager Dashboard.

Sorry to interrupt the happiness all around, setting the mentioned registry setting to 4 brought up 3 more error messages.

Third time I’ve initialized my “rented” server (Windows 2016) … and from the scratch I have an issue (the one you’re discussing about) which I cannot resolve!

My provider told me that I’ve chosen the “wrong system” … did I really?

Well it looks like the beast is a bit harder to kill since it has 9 heads and you have to decapitate them in order 🙂

First notice that «behind» every NameSvc_1234567 there is NameSvc as well which gets cloned to make the numbered one.

First, the list: sc query state= all > sc_dump.txt
Open sc_dump.txt and all numbered svc-s are at the end of file.

For each of them you need to do:
sc stop NameSvc_1234567
sc delete NameSvc_1234567

delete’s may fail, so you have to got to regedit and certify the kill 🙂 => delete corresponding registry key manually. Example: HKLM\SYSTEM\CurrentControlSet\Services\UserDataSvc_4596669

Now you need to disable «master» services (which may or may not help but it keeps things clean):

Note: 2 have «upper service» counterparts: CDPSvc — CDPUserSvc, WpnService — WpnUserService and there is the super uber service UnistoreSvc and I haven’t disabled it — yet 🙂 Disabling it should kill all others but may also get exceptions from something you do want to use. Then you just backtrack, reenable that one thing and numbered copies should be auto created again. That’s the part where you need to be stubborn, pardon persistent 🙂 There’s no surrendering and just reinstalling — step by step, back and forth (if you have to).

Before the culling run sc query SvcName and sc qc SvcName and keep the dump — that will give you display names which you can use latter to find more info. In particular WpnService is «Push Notifications System Service» so if some notifications that you actually need stop working you just re-enable it.

For the cases where the box may nail itself to the wall (== not boot) make yourself a bootable Acronis Active Undelete or Active Data Studio flash drive (check your friendly torrents :-). They have live Win8 and a small number of tools including regedit where you can load the hive from your OS and reenter what you need. Plus a 16 GB flash drive has plenty of extra space to put your own tools You can also do full key exports for all these as the ultimate backup.
