Microsoft confirmed that there was a certificate error in Windows 10 and that it could only roll back the old version if it wanted to fix the problem

Microsoft recently acknowledged a new bug in Windows 10, saying it would have to go back to the previous operating system version to fix the problem. The problem is that after updating to a newer version of Windows 10, the certificate system may not exist. For now, all the problems are caused by cumulative updates pushed by the company. The problem is primarily that updates are being made in September 2020 and later, so if the device updates the operating system that contains these cumulative updates, it may end up losing the user certificate in the system, without which many systems and third-party software will be difficult.

“When you update your device from Windows 10 1809 or later to a later version of Windows 10, the system and user certificates may be lost,” the company explains. “Devices will only be affected if they have installed any of the latest cumulative updates (LCUs) released on September 16, 2020 or later, and then continue to update from media or installation sources to newer versions of Windows 10, which are not integrated with 13 October 2020 or newer LCU releases.” This occurs primarily when managed devices are updated with outdated bundles or media through update management tools such as Windows Server Update Services (WSUS) or Microsoft Endpoint Configuration Manager. This can also happen when using stale physical media or ISO images that do not integrate the latest updates. “

Interestingly, not everyone will be affected, and Microsoft says devices that connect directly to Windows Update or use Windows Update for Business won’t encounter this bug just because they always get the latest cumulative updates, including the latest fixes.

This issue affects all Windows 10 releases released after the October 2018 update, as follows:

Windows 10 version 1903

Windows 10 version 1909

Windows 10 version 2004

Windows 10 version 20H2

Windows Server 1903

Windows Server 1909

Windows Server 2004

Windows Server 20H2

Microsoft says it is already working on a fix, but at the same time, the only way to avoid the bug is to downgrade it directly to a previous version of Windows 10 that was used before the update. Obviously, this only allows downgrades within the first 10 or 30 days of installing the new feature update. In the consumer version, for example, the standard due date is 10 days after the new feature update is installed, as long as the previous operating system files are not removed from the device. If this time limit is exceeded, all legacy backup files are deleted and the problem is only reloaded if you want to fix it immediately.

However, if the system is very important and must continue to be retained, it will have to wait, as Microsoft says it has begun work to fix the error, and once the patch is available, the company will release an update that will allow users to install a new version of Windows 10 without the risk of losing their certificates.
