Microsoft launched the Windows 10 May 2020 update on May 27. Although the feature update was tested for about 15 months before it was released to the public, it had a number of known issues when it was launched, most of which were not listed earlier. Although Microsoft blocked updates to some devices, other issues had to be patched separately.
Now, some users on the Technology Community Forum have started reporting problems with OneDrive’s Files On-Demand feature after the update to May 2020. The problem caused an error with the service, prompting “OneDrive can’t connect to Windows” prompted the user to download files that have not been synced yet, but the user noted that the “online only” file sat cannot be downloaded and the download itself is stuck. In addition, users can’t even open files that sync with OneDrive.
Microsoft responded to users who submitted support requests, acknowledging that there was an ongoing problem with the Windows 10 May 2020 update, which affected many users. The response did not specifically acknowledge the oneDrive issue, and the issue was not listed as a known issue on the update status page. The response added that the company is working on the repairs and should be completed soon.
According to the comments on the forum page, it appears that some users have successfully provided several workarounds, including resetting OneDrive or adjusting the “Cldflt” instance in the registry. However, these methods do not solve the problem for all users. The OneDrive sync client, which has been updated to the Insider version, also does not address the problem of not being able to use Files On-Demand.
At the moment, it is not clear whether the whole thing is universal. However, it is unclear whether the bug will be added to the list of known issues and whether the cumulative update will need to be fixed through its technical support page.
