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):
- Зажимаем Win + R.
- Пишем команду regedit, нажимаем ОК.
- Откроется редактор реестра, переходим по такому пути:

Второй способ попробовать отключить — через окно служб:
- Зажимаем Win + R.
- Пишем команду services.msc, нажимаем ОК.
- Откроется список.
- 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:
Onesyncsvc что это за служба
This service synchronizes mail, contacts, calendar and various other user data. Mail and other applications dependent on this functionality will not work properly when this service is not running.
I’m at 14393.447 and in services.msc it is now named Sync Host_d6ecdc (OneSyncSvc_d6ecdc) I also get parameter is incorrect. I wonder if there isn’t some sort of registry corruption. I suppose you could set the reg_dword Start to 0x4 if you really want it disabled.

Как отключить OneSyncSvc c523d на Win10?
сервис, установив его на Автоматически (Отложенный Запуск).
Попытался переключить его на отключен, но он дает всплывающее окно, говоря:
эта служба синхронизирует почту, контакты, календарь и множество других
пользовательские данные. Почта и другие приложения, зависящие от этой функции
не будет работать должным образом, если эта служба не запущена.
Так что это казалось бы совершенно бесполезным для меня. (Я даже не вошел в учетную запись Microsoft, так что настройки > счета > синхронизация параметров вкладка отключена для меня-полностью серым цветом.)
