Microsoft is investigating a known issue leading to missing system and user certificates after updating certain managed Windows 10 systems using outdated installation media through update management tools, physical media, or ISO images.
"System and user certificates might be lost when updating a device from Windows 10, version 1809 or later to a later version of Windows 10," Microsoft explains.
BleepingComputer has reached out to Microsoft for details on what are the exact certificates getting lost due to this issue but did not hear back at the time of publication.
While a fix for this issue is not immediately available as Microsoft has just started investigating it and working on a solution over the weekend, you can work around it by going to a previous Windows 10 version using instructions available here.
"You will then need to update to the later version of Windows 10 after the issue is resolved in your environment."
