System and user certificates may be lost when upgrading a device from Windows 10, version 1809 or later to a later version of Windows 10. Devices will only be affected if they have already installed any latest cumulative update (LCU) released in 16 September 2020 or later and proceed with upgrading to a later version of Windows 10 from the media or from an installation source that does not have an LCU released on October 13, 2020 or later integrated. This is especially true when managed devices are updated using outdated packages or media through an update management tool, such as Windows Server Update Services (WSUS) or Microsoft Endpoint Configuration Manager. This can also happen when using outdated physical media or ISO images that do not have the latest updates integrated. Observation Devices that use Windows Update for Business or connect directly to Windows Update are not affected. Any device connected to Windows Update must always receive the latest versions of the feature update, including the latest LCU, without any extra steps. |
If you have already encountered this problem on your device, you can mitigate it in the uninstallation window by going back to the previous version of Windows using the instructions here. The uninstallation window can be 10 or 30 days, depending on the configuration of your environment and the version you are upgrading to. Next, you will need to upgrade to the latest version of Windows 10 after the issue is resolved in your environment. Observation In the uninstallation window, you can increase the number of days required to return to the previous version of Windows 10 using the DISM / Set-OSUninstallWindow command. You must make this change before the standard uninstall window has expired. For more information, see DISM operating system uninstall command line options.
We are working on a resolution and will provide updated packages and renewed media in the coming weeks. |
