Windows update error 0x800700c1

[Artyk]

Hello,

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

I have tried many things (SFC, DISM) but to no success.
I also tried to create Windows 10 media for an in-place upgrade, but this also fails.
This forum has the most detailed instructions about these problems I have found on the net and hoping someone can help!


Issue:
When I try to run Windows update, it doesn't work and gives error 0x800700c1



I have tried the following per forum instructions:

Step 1: Run SFC Scan
This does not run and says the following:
C:\WINDOWS\system32>sfc /scannow
Windows Resource Protection could not start the repair service.

Step 2: DISM
This also does not run -- gives Error 193 (see below).
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
Step 3: ComponentsScanner
This was run with no errors.
I uploaded the results to Sysnative and ComponentsScanner.txt is attached.
Step 4: Export CBS folder
Done and attached.

Thanks for this great forum and looking at this.
Let me know what I can do to try to fix it!

Hi,

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.

DISM /online /cleanup-image /RestoreHealth
