UnistackSvcGroup--CDPUserSvc_4ec46

Question

_{Tuesday, March 14, 2017 4:02 AM}

Hello,

Running Windows 10, fully patched.

I have a service with the following parameters:

    Service Name: CDPUserSvc_4ec46
    Process Name: CDPUserSvc_4ec46
  Path to executable: C:\Windows\system32\svchost.exe -k UnistackSvcGroup

What is this service? I can not disable it.
What is UnistackSvcGroup?

I've scanned with forefront and Malwarebytes and nothing comes back as a virus.

Thanks,
Shane

The number at the end changes between systems but it seen on lots if not all Windows 10 systems since the last update afaik.

From What is the CDPUsersvc for ?

Looking at that with Process Explorer, under the Services tab of the Properties of that process;

OneSyncSvc_3e64b Sync Host_3e64b

This service synchronizes mail, contacts, calendar and various other user data.
Mail and other application dependent on this functionality will not work
properly when this service is not running.

PimIndexMaintenanceSvc_3e64b Contact Data_3e64b

Indexes contact date for fast contact searching. If you stop or disable this
serice, contacts might be missing from you search results.

UnistoreSvc_3e64b User Data Storage_3e64b

Handles storage of structed user data, including contact info, calendars,
messages and other content. If you stop or disable this service, apps that use
this data might work correctly.

UserDataSvc_3e64b User Data Access_3e64b

Provides apps with access to structured user data, including contact info,
calendars, messages and other content. If you stop of disable this service,
apps that use this data might not work correctly

Also has a https connection MS server, so looking it is OneDrive \ contacts related. Properly could do with some finishing touches on the service...
