Download error - 0x800700c1

[jschoonj]

After having a W10 x64 PRO PC sitting unused for almost a year, I am no longer able to update Windows.
I'm getting a download error - 0x800700c1.
I tried to fix this by troubleshooting and going into various CMD prompts:

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

C:\WINDOWS\system32>sfc /scannow

Windows Resource Protection could not start the repair service.


///////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Creating new install media for repair also does not work.
I was about ready to perform a clean install until I came across these forum posts.
Can anyone help me out?

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

Thanks so much for your reply!

Unfortunately the command failed.
I'll add the result as requested.
