There is an update, which does not come through WSUS, which enables OneDrive for Business to the NGSC (Next Generation Sync Client), if you have Office 2013 installed on your device. You need this update only, if you still run Office 2013
|before 09/21/2015||after 09/21/2015|
|Version 15.0.4745.1000||Version 15.0.4753.1000|
Requirement for this update is the installation of the update KB3085480, which Microsoft deployed on 9/8/15 (also via WSUS).
The update KB29758891 Update adds support for OneDrive for Business to be aware of the Next Generation Sync Client, which is available in a preview version. Devices that have this update installed will be able to hand off ownership of the synced folder to the Next Generation Sync Client
I only can speculate, why Microsoft has not provided (yet) this update via WSUS. People, who wants to deal with the preview on the Next generation Sync client (NGSC) should install this update.
