Win10 Internet certificate error

php Xiaobian Yuzai will introduce to you how to solve the Win10 Internet certificate error. When using a Windows 10 system to access the Internet, you may sometimes encounter certificate errors, resulting in the inability to access certain websites normally. This error can be caused by expired certificates, chain of trust issues, or incorrect network settings. In order to solve this problem, we can take some simple steps to fix the certificate error and ensure normal Internet access. The specific solutions will be introduced in detail below.

When updating a device from Windows 10 version 1809 or later to a later version of Windows 10, a loss of system and user certificates can occur. This is due to the device having installed the latest Cumulative Update (LCU) released on September 16, 2020 or later, and then updating to a newer version of Windows 10 from media or installation sources that did not integrate 2020 LCU released on October 13, 2019 or newer. This mainly occurs on managed devices that are updated with outdated bundles or media, such as through an update management tool such as Windows Server Update Services (WSUS) or Microsoft Endpoint Configuration Manager. At the same time, if you use outdated physical media or ISO images that do not integrate the latest updates, this problem may also occur.

Interestingly, not everyone is affected. According to Microsoft, devices connected directly to Windows Update or devices using Windows Update for Business will not experience this bug. This is because they always get the latest cumulative updates instantly, which include the latest fixes.

This issue affects all Windows 10 versions 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 version

Windows Server 1909 version

Windows Server 2004 version

WindowsServer20H2版

Microsoft said it is already working on a fix, but in the meantime, the only way to avoid this bug is to directly downgrade to the previous version of Windows 10 that was used before the update. Apparently this only allows for downgrades within the first 10 or 30 days after installing a new feature update. Taking the consumer version as an example, the standard deadline is 10 days after the new feature update is installed, as long as the previous operating system files have not been deleted from the device. If this time limit is exceeded, the system will delete all old backup files, and the only way to fix the problem immediately is to reinstall.

However, if the system is very important and must continue to be retained, you need to wait, because Microsoft said that it has begun work to fix this error. Once the patch is available, the company will release an update to allow users to install the new Windows 10 version without the risk of losing your certificate.
