OneDrive issues after update to Windows 10 2004
I recently updated Windows 10 to version 2004, and after the last update-related reboot OneDrive would keep complaining about not being able to connect to Windows--required for the Files On-Demand feature (see snapshot below).
I tried both workarounds related to cldflt.sys described in https://support.microsoft.com/en-us/office/-onedrive-cannot-connect-to-windows-error-when-accessing-files-in-onedrive-7c5b675f-555e-4aa1-b4d8-554698c2c2b9, but in my case both were checking out fine. I finally gave in & clicked Download Files, which was supposed to disable Files On-Demand and just pull down everything that wasn't there already. But the sync gets stuck immediately, claiming that it's downloading 1 out of 35 files (18MB total), except no matter how long I leave it, or how many times I restart OneDrive or logout & back in or restart the entire machine, it never moves forward...
To make matters worse, none of the files synced to OneDrive now open; I am using OneDrive to backup Desktop, Documents, and Pictures, so none of those files can be opened... Here is an example of a message thrown when trying to open a PDF on my Desktop (which, by the way, is fully sync'ed, as indicated by the green check overlay on the file's icon):
Any ideas how to get out of this pickle?
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.

I had the same problem as @HughesHall. Two Acers and two HPs were upgraded and this problem appeared only on one of the HPs. I was able to roll that one back to 1909 but I had to reinitialize OneDrive after the rollback. There is one more HP to upgrade, but I am holding off until this issue is resolved.
Is there a way to be notified when a resolution is published?
Hammer_Man I dont think anyone from MS has posted here or acknowledged the problem. They may not be even aware.... Has anyone raised a support case?
Resonate1740 I raised a support case (2117010) shortly after writing the OP--check my first reply in this thread, with one of MS replies verbatim. I must say, the way MS handles tickets is rather obscure. My original concern was answered by a virtual assistant, then passed onto a live expert (I guess that's when the ticket was open), but I don't see a way to check that ticket's status or even see my exchange with the expert (all done inside a chat-like interface from directly.com...
MStruzak We have a slightly different issue but the same cause. We have OneDrive KFM configured and we rolled out 2004. We found that Dell OptiPlex 7070 would not connect to OneDrive but other models work without issue. All our HP worked fine, Dell 9020, 7040,7050 & 7060 are fine too.
We have tried everything but we can't get One Drive to work.
I wonder why that hardware has an issue and does this point to the root cause? We have 30 identical PC's that don't work. BIOS and all drivers up to date.
Same problem here...
I also tried running this:
%localappdata%\Microsoft\OneDrive\OneDrive.exe /reset
But no success. When activating the On-Demand Files it still shows the same message, with the error code 0x80070032
due to OneDrive sync issue ( cant open , edit , copy any file in the local pc ) you need to restored to earlier build version of windows (from 2004 to 1909) until the issue solved
- far from ideal! Is this an official MS response?
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.
arganoid Yep same results but still has the same outcome. I want to use FOD and I cant!
MStruzak Same problem here.....
- Sounds like something I had seen before , MS has a workaround for this issue, although yours can still be related to some "nastiness" in the latest build.

Just an update for those who, like me, might be trying different things to get this to work again... Here is what I just heard from Support:
Apologies for any trouble caused. Yes there is an ongoing issue with that 2004 update and many users are affected with it but hopefully the engineering team will have this fixed soon as they are working on it and let's further wait for the next update.BTW, Onedrive sync client ver. 084 doesn't fix it--already tried...
- The new Troubleshooter worked like a charm for me.
- Please can you provide more info on this troubleshooter? Was it a new download via Windows Update? I do not have a troubleshooter specifically for OneDrive on my system.
