In the following article, you’ll learn what you can do to troubleshoot this error. ## Fixing error 0x800f081f with the troubleshooter Microsoft has long struggled with a paradoxical fact: Its Update Center regularly causes problems that prevent users from implementing improvements and upgrades by downloading and installing new updates. For this reason, a **troubleshooting** tool was included with Windows 10 that automatically fixes most errors, including the error 0x800f081f. To use the tool, first open the Windows settings app by choosing the **Settings** button in the Start menu or using the keyboard shortcut **Windows key + i**. Next, select the **Update & Security** section: [![Image: “Update & Security” section in Windows Settings](https://www.ionos.com/digitalguide/fileadmin/_processed_/6/3/csm_EN-0x800f081f-1_6a93ff9a93.webp "“Update & Security” section in Windows Settings")](https://www.ionos.com/digitalguide/fileadmin/DigitalGuide/Screenshots_2020/EN-0x800f081f-1.png) Windows 10 settings: Update & Security Select **Troubleshooting** from the menu on the left side of the window.

These tools are helpful when basic troubleshooting for the Update Center and other Windows features fail. For example, the [Reset Windows Update Agent](https://gallery.technet.microsoft.com/scriptcenter/Reset-Windows-Update-Agent-d824badc "Microsoft Script Center: Reset Windows Update Agent") script is very effective to troubleshoot problems that result in error code 0x800f081f. Simply download the tool using the provided download link and unzip the archived file. The file contains the ***ResetWUEng.cmd*** script. Right-click it and run it as an administrator. --- ### Note Turn off all security software except Windows Defender before running the script file because **third-party software** often blocks access to critical system components. In addition, the script could mistake the reactions of the antivirus software for actual errors. --- Run the individual components of the script by entering numbers. To resolve the 0x800f081f error, run script components 1, 2, and 3 one at a time. In most cases, the error will no longer appear during future Windows updates.

These troubleshooting tools come pre-installed with Windows and can be run from the command line. Although they don’t have a graphical user interface, they’re still very efficient. To fix the 0x800f081f error using the command line tool, proceed as follows: Right-click the Windows logo in the taskbar to open the Start menu. Select ***Command Prompt (Admin)*** or ***Windows PowerShell (Admin)***. Only one of these options will be displayed, depending on your Windows configuration or version. Once you've opened the command line tool, type the following command: ```none DISM /Online /Cleanup-image /Scanhealth ``` When you confirm your input by pressing the Enter key, Windows automatically checks for errors, which can take a few minutes. If an error is found and displayed, type the following command: ```none DISM /Online /Cleanup-image /Restorehealth ``` The detected errors are successively repaired, which can take much longer. If a message appears notifying you that the **Source files could not be found**, you have to restore them from a Windows installation DVD or an ISO file. If you don’t have the original Microsoft DVD, you can download and generate an ISO file using the [Windows Media Creation Tool](https://www.microsoft.com/software-download/windows10 "Windows Media Creation Tool: Download"). --- ### Note Always download the Windows Media Creation Tool directly from Microsoft. Some untrustworthy vendors offer fake versions that may contain malware. --- To restore the source files for the repair using the DVD or ISO file, enter the drive path for the Windows installation image in the DISM command tool: ```none DISM /Online /Cleanup-Image /RestoreHealth /Source:wim:X:\sources\install.wim:1 /LimitAccess ``` Replace the drive letter X: with the drive letter of your DVD drive or the virtual drive of the ISO file. After DISM successfully completes the repair, start the **System File Checker** in the same Command Prompt window: ```none sfc /scannow. ``` Finally, go to the Update Center. In many cases, you’ll immediately see one or more updates to install in the Update Center. You can now download and install these updates, and error code 0x800f081f will not reappear.
