Hi, please check \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CldFlt\Instances

After upgrade to build 2004, the DefaultInstance was set to CldFltUpper.

I changed the value as CldFlt, rebooted... And now the FOD function is back and fully functionnal.

Hope this will work for you too.

I had the idea to change this value as on my professional computer, I only have one instance named CldFlt and not the CldFltUpper.

MStruzakI have heard talk of a fix being worked on. In the meantime, I fixed it by doing the following:

Make 2 complete backups of everything in my OneDrive, one by copying everything in the OneDrive folder on my second PC where OneDrive still works (Windows 10 2004 has not yet been installed on there), and also by downloading everything from the OneDrive website to my main PC.

Close OneDrive app

Reset OneDrive - https://support.microsoft.com/en-us/office/reset-onedrive-34701e00-bf7b-42db-b960-84905399050c

Delete everything in the OneDrive folder

Restart OneDrive

OneDrive then synced everything successfully.

HOWEVER:

If I then re-enable Files-On-Demand, I once again get the error "OneDrive cannot connect to Windows".

If I choose “Download Files”, as I did before, it seems to work – for now.
