OneDrive for Business – which Version of the NGSC do I use?

Next Generation Sync Client Versions

I have many devices. With different operating systems. Und, no surprise, with different Next Generation Sync Clients (NGSC) on these devices.  And to the top questions, I receive on different channels, is this one:

Where do I get the newest NGSC Client, to manually install (update) it?

an my answer is always: You do not need to update it manually.

Let’s see the background: Updates from Microsoft for the NGSC do not come via Windows Update nor to Windows Software Updates (WSUS) nor through the Click to Run mechanism of Office.

The NGSC has its own Update mechanism

Microsoft used this way, to sync it’s cloud changes and also the client, not dependent on User or administrator.


  • The NGSC is syncing (this time) only with the cloud (Office 365)
  • depending of settings in your tenant and of your client OS, Microsoft do a release
  • Each NGSC Client looks once a day , if there is a new approved version
  • If yes, an automatic upload is initiated and a new NGSC will installed.
  • The installation package is small: Only 20,6 MB

and what’s the newest version?

You find the official Microsoft change log here
I have written my own change log here

Which version Do I have installed on my different devices:

Operating system NGSC Version
Windows 10 Build 16241 (Windows Insider) 17.3.6944.0627
Windows 10 Build 16237 (Windows Insider) 17.3.6944.0627
Windows 10 Build 15063 17.3.6931.0609
Windows 8.1 17.3.6944.0627
Windows 7 17.3.6944.0627

So it looks, that at this time, writing this blog post, the version 17.3.6944.0627 is the newest one. It is a guess that this version was installed with me on Windows 7 and 8.1 as an update because on these devices the registry key TeamSiteSyncPreview was set to synchronize document libraries on SharePoint Online (TeamSites, Groups, Microsoft Teams).  Besides, I do not carry out a manual update!

When you download the latest full version of Windows, you get version 17.3.6799.0327.


You do not have to download the client manually. The only requirement would be to uninstall an installation package that is customized in a company with a relatively new client
