    Sync Host error at shut down

    One drive is disabled, No store and no Microsoft account on this desktop.
    At shut down this event error will be reported
    "Sync Host 386de service terminated unexpectedly....corrective action in 10000mlsec ..restart the service
    Searching the registry results in that there is no 386de sync host service
    There are others in the registry but not this recent 386de

    In the past I did edit the START to be 4 (suggested in this forum general discussion on similar sync host errors)
    The setting was returned to 2 when no change was observed.
    This error tends to appear when external drives remain plugged in.
    Since the Nov. upgrade if externals are left in a usb3 port the system restarts. I now unplug but last night after recent Jan updates I tested by leaving in 1 Usb3 external. ...same restart routine. and the Sync Host error

    What is this background service synching to if I do not use cloud service or the store service?

    Microsoft has acknowledged the issue. It has no obvious impact - at least not on this PC.

    Remedies mentioned below, culled from various forums, do not solve it permanently...

    1. Change Bitlocker service to AUTOMATIC

    2. Change the START item in this registry key and the "3xxx" OneSyncSvc key below it to 4...

    That is the same as running the following command, which will disable People, Calendar and Mail apps...
    sc stop "OneSyncSvc"
    sc config "OneSyncSvc" start= disabled

    3. In SETTINGS|PRIVACY|CONTACTS, turn off all toggles.

    Bottom line: ignore the error.

    "Bottom line: ignore the error."

    Seems like this has been the 'routine' for many little things.
    Since I inquired about this- the event error has not been repeating. In fact, I'm almost event error free
    The performance reliability chart has a high level line and no red dots
    BUT each notice of an update has a 'okay, get ready' attitude here.
