Error when running DISM /Online /Cleanup-Image /RestoreHealth - error 0x800f0906

Hi,

Thank you for reaching us on the forum.

• Which update you are unable to view?
• Which security software is installed on your computer?
• Which Windows update you are trying to download and install?
• Do you remember the KB article of the update?

Do get back to us with all these information and we will be happy to assist you further.

Regards.

I don't have the update mentioned in method 2 so I downloaded it and tried to install.  I got a message saying that update was not associated with my computer which has windows 8.1.

Hi Kevin,

Did you make any changes to the computer prior to the issue?

This error code occurs because the computer cannot download the required files from Windows Update.

There seems to be two files which are corrupt/not present, check if you can find the following files on your computer netprofmsvc.dll (C:\windows\system32) & wmiprvsd.dll (C:\windows\system32\wbem & c:\windows\winsxs..)

Method 1:

Run the System File Checker (SFC) scan. Follow these steps:

a. Boot to the desktop view.

b. Press Windows key + X

c. Select command prompt (admin).

d. Type sfc /scannow and then press ENTER:

The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.

Method 2:

Check if the following update is installed:

www.support.microsoft.com/kb/2811660

If the update is not installed then you can download and install it manually.

Refer:

Hope this resolves the issue. If the issue persists, you can write to us and we will be glad to assist you further.

Hi All,

I have encountered these same sfc and dism errors on two occassions with win 8.0 fully updated. By trial and error I was able to resolve these issues by applying sfc /scannow -> reboot -> dism /online /cleanup-image /restorehealth -> reboot, cyclically as many as 3 cycles until finally sfc finds no integrity violations. So I would keep cycling as long as you can stand it because it may require more than 3 times depending on your circumstances.

I hope this works for you guys too.

Best Regards,

@Tom1066: yes, I downloaded the ISO image and attempted to repair the files and when that did not work, I gave up and started the installation instead.

And surprise surprise it gave me the option to keep my data and apps. WOW. It looked like a "normal" Windows installation including several times of automatic restarts. I was away from the laptop, while this was happening, just saw the warning. When it finally started it had a low resolution driver for my screen. I tried to update it manually, but within 5-10 minutes Windows had automatically corrected that. Great! The only other thing I observed so far is that it had to index my Outlook 2010 pst files again. And that is such a minor price to pay. Even my browsers work with the extensions that were there prior to the re-install.  I was amazed.

Afterwards I ran WU and there were about 50+ additional important updates that installed on top. Maybe that could have been included in the original downloaded package, but in the bigger schemes things: GREAT progress from MS on this front. Big THANKS!

BUT.......

I just wished someone in the community had told me this, when I started tinkering around with DISM. Because my main hesitation around the re-install was the potential effort to save, restore data and  install the apps.

This great experience does not remove that I am still irritated that you upgrade from 8.0 to 8.1 for free. And if 8.1 fails the only "free" way to re-install is to install 8.0 again and then upgrade!!! And from my vantage point it looks like my hard disk is fine (based on CHKDSK and 3rd party software), so it comes across as a problem Microsoft caused and cannot help the user recover from. So having me pay a price (list price quote from MS: $199 for Pro) for this seems strange. IMO the recovery path (re-install 8.0 and then upgrade to 8.1) should have been pointed out in BIG RED letters at the time I did the free upgrade. There should have been absolutely NO doubt. Yes it might have been in the license agreement and I accepted that. BUT that does not seem like a very customer focused approach even when it's fully legal. The net result is that after about 34 years mainly on this platform I will consider another platform, when I get another laptop within one year.

I did raise the second issue a couple of weeks ago in a separate posting in the community and no Microsoft employee responded yet.
