Once you restart your computer you will be good to go.
You can upgrade to this version of Windows 10 through the standard Windows update process. That means that this will not work on things like Windows 7, 8 or Mac OS. If you want to utilize Files On-Demand this is a minimal requirement. The Windows 10 Fall Creators Update (version 16299.15 or later) is required along with OneDrive build. I have been working with Files On-Demand for a good amount of time and here are some things that you need to know. In my opinion, this is one of the best solutions rolled out to us in a long time. You then have the option to sync files as you wish or by choosing to bring them offline or when you double click to open a cloud file, it will automatically download it for you. You access these files right within your desktop and file explorer. With this feature you don't need to change the work because you see your cloud files just like your regular files. This means you can view all your files that you have synced without having them on your device. Files On-Demand allows access to all of your files without using storage on your device. Files On-Demand is a game changer for how you interact with your content within Office 365.
