Hello,

I'm having an issue doing windows updates. It's erroring out with 0x800700c1. Tried running both SFC and DISM and getting the following errors:
Code: 
C:\WINDOWS\system32>sfc /scannow

Windows Resource Protection could not start the repair service.

Code: 
C:\WINDOWS\system32>Dism /Online /Cleanup-Image /RestoreHealth

Deployment Image Servicing and Management tool
Version: 10.0.19041.844

Image Version: 10.0.19045.3516


Error: 193

%1 is not a valid Win32 application.

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

I've attached the DISM, CBS logs.

Thank You

Thanks, could you please zip up and provide all the logs from %systemroot%\Logs\CBS? It looks like the your log has rolled over so most of the information will be part of the *.persist.log files.
 
Thanks, could you please try the attached below? If DISM fails again, could you please provide all the CBS logs like you did in your previous post?
