Windows update error 0x800700c1

cdmelloca · Dec 28, 2023

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:

Code:

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

Code:

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.

Warning: This fix was written specifically for this system. Do not run this fix on another system.

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.

Code:

DISM /online /cleanup-image /RestoreHealth
