A Microsoft file hosting and synchronization service.
Hi Harry,
I would first like to explain that the latest version of OneDrive for Business that comes with Windows 10 is the Next Generation sync client. Support for SharePoint sites is coming in the future.
For now, you would need to install the legacy sync client to sync SharePoint sites. To answer your concern, both sync clients can be installed side-by-side. You do not need to uninstall your Next Generation sync client.
If you have an Office 365 subscription that includes fully installed desktop applications, you can download and install Office via the Office 365 Portal that includes the legacy sync client inside.
If you do not have an Office 365 subscription that includes fully installed desktop applications or you would like a standalone legacy sync client installer, please refer to the link below:
How to install the OneDrive for Business sync client for SharePoint 2013 and SharePoint Online.
I have also provided an article to help you differentiate between the two sync clients:
