DISM and SFC are command line tools that can, in the best-case scenario, be used to repair Windows. SFC stands for “System File Checker”, DISM for “Deployment Image Servicing and Management”. The SFC and DISM repair tools perform a system file check and can restore corrupt files. Here’s how to use them:
Step 1: Open the command prompt with administrator rights by pressing [Windows] + [R], typing “cmd” and then pressing [Ctrl] + [Shift] + [Enter].
Step 2: Now type the CMD command “sfc/scannow” and press [Enter].
Step 3: Next, type the following commands and press [Enter] after each command: “DISM.exe/Online/Cleanup-image/Scanhealth”and“DISM.exe/Online/Cleanup-image/Restorehealth”.
Step 4: Close the command prompt and reboot your computer.
Step 5: Check if the error still occurs during the update.
