Nothing to be fixed

Error: 0x800F0831

and no updates found!

0x800f0831 indicates corrupted incomplete updates.

FATAL: CBS called Error with 0x800f0831

 [HRESULT = 0x800f0831 - CBS_E_STORE_CORRUPTION]
Failed to resolve package [HRESULT = 0x800f0831 - CBS_E_STORE_CORRUPTION]
Failed to get next package to re-evaluate [HRESULT = 0x800f0831 - CBS_E_STORE_CORRUPTION]
Failed to execute execution chain. [HRESULT = 0x800f0831 - CBS_E_STORE_CORRUPTION]

WER: Generating failure report for package: status: 0x800f0831, failure source: Execute, start state: Staged, target state: Installed, client id: DISM Package Manager Provider To resolve this problem, use the inbox Deployment Image Servicing and Management (DISM) tool while ONLINE wired connection.

Then, install the Windows update or service pack again.

Open an admin command prompt. To do this, open Start menu or Start screen, type Command Prompt, right-select Command Prompt, and then select Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or select Allow.
Type the following command, and then press Enter.

DISM.exe /Online /Cleanup-image /Restorehealth

It may take several minutes for the command operation to be completed.

Then run windows update troubleshooter

An in-place "repair install" of the latest Windows 10 should fix the problem. Download Windows 10 as an ISO image from Microsoft ("Create Windows 10 installation media"), mount the ISO image, and run the installation from there per this article. (The installation should preserve all your files, apps, and settings, but check your backups beforehand, just in case.) The process backs up your current Windows installation, so once you're satisfied everything's good with the new install, you'll probably want to run Disk Cleanup on your C: drive with the "Clean up system files" option to free up the space.

ok thanks

I could not understand what is it

Tell me about the word below

FATAL: CBS called Error with 0x800f0831

From what I can see the CBS_E_STORE_CORRUPTION error indicates the update store in Windows is corrupted, or at least Windows Update thinks it is. I believe the repair install will bypass this problem by giving you a fresh new error-free Windows installation.

I tried to run Dism but my computer hang up. Is there any troubleshooting guide to solve this issue?

I found this, but that's about it. You can try the Windows Update troubleshooter, as @speedstep suggested, if you haven't already. My suggestion of the repair install (I promise I won't mention it again) doesn't so much solve the problem as bypass it -- it backs up your existing Windows installation (corruption and all) and replaces it with a fresh install, preserving files, apps, and settings.

Hi
