My Windows 10 client meets trouble with Windows update. It shows that failed install update as below


I tried:

  • Re-update many time, Windows just rollback after the restart. The update process still fails

  • Rename & Clean data update folder C:\Windows\SoftwareDistribution

  • Download & try to install offline these packages from Microsoft

  • Restart all related services: Windows update, Cryptographic services, Background intelligent transfer service, msiserver

  • Run DISM command (no error)

  • Re-install all .Net on Programs and Features

I attach more bug log that I collected:






After a month or more of trying all the standard fixes I was finally able to solve my Windows Update failure problem that displayed error code 0x80070003. I am posting here in case others may benefit. It appears if you use Macrium Reflect software this may help you but I could not confirm that the problem was caused by Macrium. So whether you use Macrium or not see if this helps you.

  1. In the Registry Editor (click the Start Menu icon and type regedit), go to this location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WIMMount

  2. FIrst thing to do is make a backup of this entry in case anything goes wrong. Right click on WIMMount and select Export and save the backup somewhere.

  3. Now click on the top level WIMMount entry (if you expand it you will see Instances and WIMMount sub-directories but we will not be using those) and in the right side panel you should see 11 or so entries.

  4. Find the entry with the name “ImagePath” and make sure the Data column shows this: system32\drivers\wimmount.sys

  5. If it does not say this, click on “ImagePath” and change the Value data field to system32\drivers\wimmount.sys
    In my WIndows 10 registry, this entry showed something different so I changed it. I confirmed this entry on my two other Windows 10 PC’s.

  6. Finally, check to make sure the wimmount.sys file is in this location: C:\Windows\System32\drivers\wimmount.sys

If you didn’t have the problem stated above, I suggest using the SetupDiag tool located here:[6921c9c1f0]

This is what I used to find my problem with wimmount.sys above. You just double click SetupDiag.exe and after it runs it will create 3 files in the same folder as SetupDiag.exe. Open the SetupDiagResults.log file in Notepad and it should give you a clue as to why Windows Update failed.
