Hello! My name is Mostafa, and I will try my best to assist you with this so that you find a satisfactory solution.

I’m sorry that you are experiencing this issue. Error code 0x800f081f is typically related to a problem with the Windows Update components or corrupted system files on your computer.

Please follow the steps below:

1. Run the Windows Update Troubleshooter:

• Click on Start, then select Settings > Update & Security > Troubleshoot > Additional troubleshooters > Windows Update > Run the troubleshooter.
• Follow the on-screen instructions to complete the troubleshooter and check if it fixes the issue.

2. Run the DISM (Deployment Image Servicing and Management) tool:

• Open Command Prompt as an administrator.
• Type the following command and hit Enter: DISM.exe /Online /Cleanup-image /Restorehealth
• Wait for the command to complete (this may take some time).
• Restart your computer and check if the update installs successfully.

3. Run the System File Checker (SFC) tool:

• Open Command Prompt as an administrator.
• Type the following command and hit Enter: sfc /scannow
• Wait for the command to complete (this may take some time).
• Restart your computer and check if the update installs successfully.

4. Clear the Windows Update cache:

• Open Command Prompt as an administrator.
• Type the following commands one by one and hit Enter after each command:

arduino

Copy code

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

• Rename the Software Distribution and Catroot2 folders by typing the following commands one by one and hitting Enter after each command:

mathematica

Copy code

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

ren C:\Windows\System32\catroot2 Catroot2.old

• Type the following commands to restart the services:

sql

Copy code

net start wuauserv

net start cryptSvc

net start bits

net start msiserver

• Restart your computer and check if the update installs successfully.

5. If you still have issues try performing an In-place Upgrade. It will definitely help in resolving update errors. Performing this can repair broken operating system files while your personal files, and installed applications, will not be removed.

Answer 2

Mostafa,

I have this problem with the last two Windows "Cumulative" updates - 2023-04 (KB5025182) and 2023-05 (KB5026372), so I will try your solution of clearing the Windows Update cache. I have already tried multiple times running both the DISM and SFC commands, but those have not worked. I also thought there was a method of downloading a Windows Update and manually installing it - is that an option? If so, where do I find the file(s) to download?

Thanks.

Answer 3

I tried every step and it still tells me there is an error while installing. I have tried several other ways and I also can't get my computer to fix the corrupt configuration registry database either which I'm pretty sure is also affecting the update

Answer 4

If the update is not being installed manually or from Windows update there is a site windows companion assist so go there and click on the first link and download it and run it as administrator it will download windows 11 once again but your data will not be lost that's a good point and it will update your pc if any update is remaining

Answer 5

Thanks, but I've also run the "Clean Install" of Windows 11 twice, and it does earlier updates, but the most recent two keep failing. On this last attempt, using the commands above to clear the Update cache, it completed the download of the update (before it stopped at 35%) and it went through the first 10% of updating (after restart) before it failed.
