[SOLVED] Win 10 Update KB5030211 Error 0x800700c1 / SFC/DISM errors

[Arcinius]

Windows update KB5030211 fails to download with the error code 0x800700c1.
I am on Windows 10 22H2 x64 (10.0.19045.3324)

The things I've tried are
chkdsk which found no errors
sfc /scannow which returns "Windows Resource Protection could not start the repair service."
dism /online /cleanup-image /restorehealth which returns
Error: 193
%1 is not a valid Win32 application.

I also tried to do an upgrade repair with the Media Creation Tool which results in a failed installation upon reaching 100% before any restarts.

Any help is very appreciated.

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

Everything is working now, DISM was able to be run and completed and the Windows update is no longer there showing an error. Thanks so much for the help.
