Microsoft regularly releases major updates for Windows 10 twice a year. After releasing a major update, Microsoft gets to work on improving it by fixing various bugs, releasing security patches, and sometimes adding new features.

The most recent major Windows 10 Updates were versions 2004 and 20H2 (May 2020 Update and October 2020 Update). This update included many security updates for Windows Apps, Windows Office Media, Windows Fundamentals, Windows Cryptography, Windows Kernel, Windows Virtualization, Windows Media, and so on.

In this build, Microsoft removed the old Microsoft Edge browser and replaced it with the new Chromium-based Edge.

Nevertheless, not everything is sunshine and rainbows as there are still a few known issues in this update, including one that causes system and user certificates to be lost when updating a PC from Windows 10 version 1809 or later to a later version.

Unfortunately, the latest updates still don’t prevent  Windows Update Error 0x8000ffff from occurring. According to user reports, most of them encounter error 0x8000ffff while trying to install a standard update or while updating apps from the Microsoft Store. In addition, some users have encountered this error while installing updates after a system restore. Also, you may get an error 0x8000ffff if Windows updates and locks the Windows store.

So, you may get error 0x8000ffff while updating windows via Windows Update, which will prevent some updates from installing. You may also get this update while updating apps from the Windows store. And, finally, you may get this error while creating a system restore point.

Windows users have been experiencing this error since 2018 as many users complained getting it when trying to install 2018-01 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4058258). However, it must be noted that this issue occurs not because there’s an inherent problem with Windows, but due to specific reasons.

Therefore, you may experience error 0x8000ffff as a result of a malware infection, faulty or outdated device drivers, incorrect date and time settings, corrupted Windows cache, missing or corrupted system files, and corrupt  Windows Registry entries.

Some have suggested that error 0x8000ffff has nothing to do with corrupted Windows system files, but everything to do with third-party applications, such as antivirus programs. So it’s a good idea to temporarily disable your third-party antivirus program and try updating Windows.

Still, according to Microsoft, you may get an error 0x8000ffff when its update servers are under heavy load and also if the servers are down. If that’s the case, then it’s recommended to wait for a day and if the issue isn’t resolved by then -- look for ways to fix it.

Another significant problem with getting error code 0x8000ffff is that it will prevent you from installing other updates, which will likely leave your computer vulnerable to security exploits and other issues. Therefore, fixing error 0x8000ffff is vital to keep your computer secured and protected from online threats and running smoothly.
