My laptop came with Windows 8 pre-installed. I installed all Microsoft updates, including that to 8.1 and have continued to do so.

The latest update which has come through is KB 2912355 which is a massive 890 MB. This has refused ti install, despite many attempts.

The system reports error 800F081F. Having looked at Microsoft online support, I have tried the following :-

DISM.exe /Online /Cleanup-image /Restorehealth

this failed with the following comments :-

The restore operation failed. Either the repair source was not found or the component store cannot be repaired.
Error: 0x800f081f

I have therefor tried the next suggestion under 'repair a Windows image' :-

Dism /Online /Cleanup-Image /ScanHealth

This reported :-

The component store is repairable.
The operation completed successfully.

I next ran :-

Dism /Online /Cleanup-Image /CheckHealth

This also reported :-

The component store is repairable.
The operation completed successfully.

I therefore next ran :-

Dism /Online /Cleanup-Image /RestoreHealth

The output was :-

The restore operation failed. Either the repair source was not fou
onent store cannot be repaired.

Error: 0x800f081f

DISM failed. No operation was performed.
For more information, review the log file.

The DISM log file can be found at C:\WINDOWS\Logs\DISM\dism.log

C:\WINDOWS\system32>Dism /Cleanup-Image /RestoreHealth

Deployment Image Servicing and Management tool
Version: 6.3.9600.16384
Error: 87
The cleanup-image option is unknown.
For more information, refer to the help by running DISM.exe /?.

I did have a look at the DISM help, but the options are so many and so complicated that I didn't get anywhere.

According to Microsoft, I have an image which is repairable, but nothing they have suggested worked!

I'd be very grateful if anyone could suggest what to try next!

    Open a command prompt as administrator, and run this command: sfc /scannow. Post the command output when done. Then upload somewhere (e.g. ge.tt/about) the CBS.log file (usually located in C:\Windows\Logs\CBS) and post here the resulting link. – and31415 May 10 '14 at 9:13

How about downloading the Windows 8.1 ISO?

From this article:

http://www.howtogeek.com/186775/how-to-download-windows-7-8-and-8.1-installation-media-legally/

Once the ISO is on your computer (the Downloads folder is a good place for it) mount the ISO and find and run Setup. The ensuing process will be automatic and should work well. Takes a while, of course.

This should override any problems, and give you the Update to 8.1.

The download may be corrupt. Try stopping the Windows Update service and deleting the files in:

C:\Windows\SoftwareDistribution\Download

Open Windows Update and check for updates again.

  1. Launch a Command Prompt with administrator privileges

  2. Run the following command:

    dism /online /remove-package /packagename:Package_for_KB2919355~31bf3856ad364e35~amd64~~6.3.1.14
    
  3. Once step 2 is completed, run this command:

    dism /online /cleanup-image /startcomponentcleanup
    
  4. Try to install the Windows 8.1 update manually

There are multiple threads about corruption or corrupted files that prevent the Windows auto update files from downloading and completing the installation. I tried it all: DISM commands, SFC, the Troubleshooting tool (Update reset), etc.

The only thing that worked was to use Windows installer to repair the installation. I was ready to do a reinstall of Windows 8/8.1. The previous link lets you create an installation media with USB drive or a DVD, and do a totally non-destructive repair of your Windows 8.1 installation. It keeps all your files and installed applications. You must choose the right version for your PC.

You can follow a helpful guide to let you proceed. It includes temporary key-codes for Windows to allow it to proceed. (These will let you install Windows, but will not activate it (you can use your existing key-code that you can use a tool to find).

  • This does not really answer the author's question. You just confirm you had the issue also then reference a third-party website which has hostile advertisements. – Ramhound Apr 20 '15 at 11:21
