Windows update error 0x800700c1

[cdmelloca]

Hello,

I am having trouble updating my computer with Windows Update as it errors out with "0x800700c1"

I have tried resetting the components and still does not work. I have also tried DISM but this fails with a different error:

C:\WINDOWS\system32>DISM /online /cleanup-image /RestoreHealth

Deployment Image Servicing and Management tool
Version: 10.0.19041.844

Image Version: 10.0.19045.3448


Error: 193

%1 is not a valid Win32 application.

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

Attached is the CBS.log and DISM.log

OS Name:                   Microsoft Windows 10 Pro
OS Version:                10.0.19045 N/A Build 19045

Any assistance is greatly appreciated! Thanks in advance!

Hi and welcome to Sysnative,

Step 1. Download

SFCFix and save it to your desktop.

• Save any work you have open, and close all programs.
• Download the attachment SFCFix.zip and save it to your desktop.
• Drag the SFCFix.zip file over the SFCFix.exe executable and release it.

• SFCFix will launch, let it complete.
• Once done, a file will appear on your desktop, called SFCFix.txt.
• Post the logfile (SFCFix.txt) as attachment in your next reply.

Step 2. Run the following DISM command and post the result. If it fails attach a new copy of the CBS log.

DISM /online /cleanup-image /RestoreHealth
