[SOLVED] Windows Update [error code 0x800700c1]

[Alexei]

Hello,

I am looking for help with a Windows Update problem - error 0x800700c1
I saw a post with the excat same problem in the forum, and as provided by your tutorials (and the fact that i understand only the basics of computing) i proceed as required by the instructions

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:

Code:
C:\Windows\system32>sfc /scannow

Protección de recursos de Windows no pudo iniciar el servicio de reparación.

Translation:

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: 10.0.19045.3324

Error: 193

%1 no es una aplicación Win32 válida.

Translation:

C:\WINDOWS\system32>Dism /Online /Cleanup-Image /RestoreHealth
Deployment Image Servicing and Management tool
Version: 10.0.19041.844
Image Version: 10.0.19045.3324
Error: 193
%1 is not a valid Win32 application.

---

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.

Let me know if you need any other info.
As the other guy in 2023 said:

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

Sorry for any language inconvenience, English is not my first language.

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.

DISM /online /cleanup-image /RestoreHealth

YESSS!

Both DISM and SFC Scan works now.

I'm gonna try updating windows later today and give you an update of the results.
Thank you very very much!

Hi,

You're welcome. Glad to hear the issue has been resolved.

In this case the Servicing Stack was corrupt, so I have recplaced it with a known good copy.
