Error 0x800703e6 - is there actually a fix for this

I believe the following is the core issue we need to deal with. Until it's fixed, the image can't be repaired/serviced, and a repair install wouldn't work.

2023-01-02 01:00:02, Info CBS Failed to load Core DLL from path: C:\windows\winsxs\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.19041.1220_none_7e21bc567c7ed16b\\cbscore.dll [HRESULT = 0x800703e6 - ERROR_NOACCESS]

Let's check if the servicing module is in good condition:

Copy the following line and paste it into Command Prompt,

• certutil -hashfile "C:\windows\winsxs\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.19041.1220_none_7e21bc567c7ed16b\cbscore.dll" sha256
  

The output should be exactly as below:

SHA256 hash of C:\windows\winsxs\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.19041.1220_none_7e21bc567c7ed16b\cbscore.dll:

CertUtil: -hashfile command completed successfully.

 

Error 0x800703e6 - is there actually a fix for this

Hi Dante,

It sounds like your AV is blocking DISM/SFC, which, in turn, generates the error 0x800703e6. I see four Symantec kernel drivers running. Have you tried uninstalling Symantec products to see if that helps? If that resolves the issue, you can install Symantec later (until then, Microsoft Defender AV will protect your computer.)

CBS & DISM logs



Follow these steps to collect the CBS logs.

1. Open the folder “C:\Windows\Logs\“
   
2. Select the two folders, namely, CBS and DISM.
   
3. Right-click on the section, and click Send to → Compressed (zipped) folder.
   

Windows cannot create the Compressed (zipped) Folder here.



Do you want it to be placed on the desktop instead?

Windows update fails with 0x800703e6

Hello Narmy

Im Juliet and Im happy to help you

Error code 0x800703e6 typically indicates a problem with Windows Update or a corrupted system file.

I would suggest you try to Run the Windows Update Troubleshooter. Windows has a built-in tool to troubleshoot and fix common Windows Update errors. You can access it by typing "troubleshoot" in the Windows search bar and selecting "Troubleshoot settings." From there, select "Windows Update" under "Get up and running" and follow the prompts to run the troubleshooter.

I hope this helps! Let me know what happens
