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 this Support article, 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?

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...

@janvanwaeyenbergh You have linked to the same article the OP linked to where he said he had already tried that.

@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
Delete everything in the OneDrive folder
OneDrive then synced everything successfully.
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.

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

Same problem here...
I also tried running this:
But no success. When activating the On-Demand Files it still shows the same message, with the error code 0x80070032

@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.
06-18-2020 01:14 PM
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?
06-19-2020 06:49 AM
@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...
06-19-2020 06:58 AM
We have premier support through enterprise. Ill give it a go there and keep you posted. @MStruzak
06-19-2020 12:15 PM
I replied to an email from Support, and got an answer back asking for very basic details, as if my entire exchange with the "expert" the other day was not part of the ticket at all. I brought them up to speed on everything, will see what they say...

@MStruzak I’ve also noted that although all my environment is deployed via Intune and my office apps are set to current preview, I seem to have a much newer OneDrive client than the desktops with issues. I seem to have an insider update of 20.103.0521.0002 while the others have 20.064.0329.0008 Or older. All the office Apps are up to date on both machines and the same with windows updates. Why does this one surface laptop that KFM works on have a insider version?
i can’t find a download to try on other machines.

@HughesHall I just managed to install 20.103.0521.0002 by selecting the insider button in OneDrive settings. However, it has not fixed the issue.
06-21-2020 05:15 PM
@HughesHallTwo computers that I updated had the same version of OneDrive. The error occurred only on one, so I think it is a Windows Update problem, not with OneDrive.
06-22-2020 12:00 AM
@Resonate1740 Thanks for the update, it seems there is no obvious reason for the issue. It works on some machines and not others.
We now have user who it works for but not others on the same machine!

Same question. This problem suddenly happened on yesterday. My system version also is 2004. Have you solved this problem, sir?

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.

@Josep1190 This didn't fix my issue as the OneDrive app will not even run on the PC
After changing the key, it still would not run

@Josep1190Below is a snapshot of the registry on a machine that upgraded successfully with the DefaultInstance set to CldFltUpper. The problem must be elsewhere.
06-22-2020 09:14 PM
@Hammer_Man Hi, sorry it does not help you. But as said to @HughesHall my reply and solution was for @MStruzak who described my exact same problem. You said in your post yours was the same as @HughesHall, which is not mine. At least two users solved their problem using my trick.
Good luck solving your particular issue. I knows each situation is unique.

@Hammer_Man I've started a new post for my specific issue:

We found the solution to our issue of OneDrive not starting, it was the InTune Shared Desktop policy that is an on or off setting but it set 30 policies up including disabling OneDrive!
Why you'd want to disable OneDrive on a Shared Desktop in a InTune environment, I don't know but here is the article on what this policy does:
Gotcha! Just one of the numerous setting this one policy makes
Admin Templates>Windows Components>OneDrive
Prevent the usage of OneDrive for file storage
06-24-2020 09:37 PM
@Josep1190, you're a Genius! My \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CldFlt\Instances was also set to CldFltUpper, and although I did not have a pre-upgrade copy to compare, I just followed your recommendation: changed to CldFlt & rebooted. Now everything works again!
Thank you very much!

This fix worked for me as well. My OneDrive Personal and OneDrive Business both were not syncing after the upgrade. This registry change did the trick. Nice sleuthing on that. Also, thanks to the OP for providing a very clear write up and description of the issue.

I hope somebody from Microsoft with at least a little bit of competence can address this issue.
Microsoft constantly drops the ball on its Windows 10 updates and could care less about consumers or small businesses.
I'm about ready to drop Windows altogether and switch to the only crap option of Linux, in addition to my personal and business subscriptions of Office 365 since it seems impossible to have a reliable computer with MS's poor customer support.
Call their customer service for any reason or chat with them in a chat and you're bound to get the most incompetent of people. The corporation as a whole doesn't care about its consumers because they have a contract with nearly every government agency in the US as well as the larger enterprises.

@MStruzak I'm also having this issue after the install of 2004. It's effectively killed most of the files stored in my local OneDrive folder because they no longer open or sync. I've tried all the support tips of pausing sync / unpausing, uninstalling / re-installing different versions. What a massive waste of time for so many people!
06-30-2020 12:42 AM
Hi, Have you tried this fix ?
07-02-2020 04:35 PM
Windows 10 gave me a notification saying that a troubleshooter for OneDrive needed to run. After running the troubleshooter and rebooting, I could turn on Files on Demand without the error occurring.
I'm now finding that most of the time (although not always), when I right click on a file in OneDrive to change its sync mode, the context menu disappears within less than a second. This isn't happening with files outside of OneDrive.
Second, I'm finding that it now appears to be impossible to turn off Files on Demand. When I uncheck the box, a message pops up reading "Disable Files on Demand. All OneDrive files and folders will download to this PC". There are OK and cancel buttons. Regardless of which one I click on, the Files on Demand checkbox gets re-checked.
07-02-2020 09:43 PM
@MStruzak I just started my PC and got a notification for running a Troubleshooter to fix my OneDrive files on demand connection and sync issue. I ran it. Restarted and BANG. It all works! Thank you so much for responding to this quickly. So pleased :)
