Hi All,

The PC runs Windows 10 version 20H2 OS Build 19042.1110

Issue:

Step 1: Run SFC Scan

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

Hi,

Thank you for your update

Step 1- Done
Note -- the attachment was called SFCFix.zip so that was what I dragged to the SFCFix.exe.
Result attached -

Step 2-
DISM command ran and completed - error on source files - Result attached (DISM Log and CBS log)



For your reference; I am able to run SFC /scannow but some files are corrupted - Results are attached - CBS log
