Windows 10 update error code 0x800f0831
on Windows

Hello. For a past few months, Windows 10 tries to install the latest updates but always fails with error code 0x800f0831. I am running 1903 currently. Is there anything that can be done to solve this? It is really frustrating, please help.

Error code 0x800f0831 is an error people can encounter while using the Windows Update service. Indeed, it’s not pleasant to see this, as it means that none of the cumulative, security or other updates can be installed successfully. Most recently, users encountered this error when trying to download the KB5012599 update for Windows 10/11.

Apart from 0x800f0831, there are hundreds of Windows Update errors (e.g., 0x80070103, 0x80073712, or 0x80070541), but most of them can be easily resolved. Usually, they are triggered by Windows Store cache,[ref en-3] inaccessible Windows Update service, antivirus software, or some damaged update files.

In most cases, Microsoft reacts to people’s reports related to Windows Update service crashes immediately and either fixes the issue automatically or provides manual guidelines explaining how to deal with them.

However, there are no official patches to fix the 0x800f0831 error, so we will try to help you. Having the latest updates installed is very important to maintain a system’s performance and security. If each attempt to install Windows[ref en-2] updates leads to the error mentioned above, try to perform the following steps first:

• Reboot your PC to a normal mode;
• Disable your anti-virus temporarily;
• Check your internet connection (perform a speed test)
• Check your time and date settings.
• Install [d1] and run a full scan with it to resolve underlying Windows issues that could cause the error.

If none of these methods helped, please refer to the following fixes.

These are the methods that helped for most of the Windows users who have been struggling with the installation of Windows updates. If they did not work in your case, we would also recommend checking if the Date & Time settings are correct. Sometimes, incorrectly set Date and time may collide with Windows Update and Windows Store[ref en-1] services, which is why the updates fail to download/install.
