Microsoft Windows displays the error 0x800f0831 when a system update fails to install. The most common reason this happens is that your system files are corrupt. You also get the above error because your internet connection isn’t working, your PC is using the wrong date and time, Windows’ update cache is corrupt, and more.
However, you can fix those problematic files and apply a few other solutions to resolve your update issue in Windows. Here’s how.
Check Your Internet Connection
The first thing to check when a Windows update fails to download or install is your internet connection. Windows relies on your internet connection to successfully update files. An inactive connection interrupts that process, causing your updates to fail.
Launch a web browser on your PC and open a site. If you can access the site, your connection is working. If your site fails to open, your internet connection has a problem.
You can fix your connection issues by rebooting your router, reconnecting your PC to your network, and using other internet troubleshooting tips.
Fix Windows Update Error by Turning Off Your Proxy
Your PC’s proxy routes your internet traffic via a third-party server, sometimes causing problems with your internet-enabled features, like Windows Update. In this case, disable your proxy server and see if your issue is resolved.
- Open Windows Settings by pressing Windows + I.
- Select Network & internet in the left sidebar.
- Choose Proxy on the right pane.
- Turn off the Automatically detect settings option.
- Select Set up next to Use a proxy server and turn off the Use a proxy server option.
- Run a Windows update.
Restart Your Windows 10/Windows 11 PC
Your system’s minor glitches can cause Windows updates to fail. In this case, you can reboot your PC to fix many minor problems with your operating system.
Make sure to save your unsaved work before turning off your computer.
- Open the Start menu by selecting the Start button or pressing the Windows key.
- Select the Power icon and choose Restart to reboot your PC.
