Step 1: Open Command Prompt as an Administrator
As discussed above, you are required to start the Command Prompt under administrative; otherwise, you will fail to run the DISM command.
Step 2: Check System Health
Start by checking system health by issuing the command
copy code
DISM /Online /Cleanup-Image /CheckHealth
Press Enter. This will scan your Windows image quickly for problems. You’ll get a message stating whether your image is healthy or if there are known issues.
Step 3: Check for Corruption
If you see potential problems, then the next step is to check in more depth for corruption with the following command:
DISM /Online /Cleanup-Image /ScanHealth
Press Enter. This command takes a little time, be patient. DISM will check your system for system component store corruption.
Step 4: Restore Health of Your System
If corruption has been detected during the scan, you will have to restore the health of your system by following the line using this code:
DISM /Online /Cleanup-Image /RestoreHealth
Press Enter. This will start the repair process. It will take some time. Do not interrupt this process. Once the DISM repair process is complete, you can see a success message or details of any other issues.
Step 5: Checking the Results
Now you will view a summary of the process after it is complete. When you run DISM, if this tool detected and repairs some problems, you will discover a successful message. When some files could not be repaired, execute the instructions on what to do further.

More Tips in Using DISM

Run SFC After DISM: When you run the DISM, it becomes very essential to run the SFC to scan for extra missing files, which is through the command prompt by inputting the command
bash
sfc /scannow.
Internet Connection: To complete the repair, DISM may need to download some files. The one executing the command requires a stable internet connection for the successful execution of these commands.
Be Patient: Many commands under DISM take an ample amount of time for execution. One should not interrupt such processes; sometimes, patience is called for.
Use DISM with a Source: If DISM can’t find the files, it can take repair sources from one source. That can be a Windows installation media: USB or DVD. You can use this command:
DISM /Online /Cleanup-Image /RestoreHealth /Source:C:\\RepairSource\\Windows /LimitAccess
Replace C:\\RepairSource\\Windows with the path to your actual source files.
Update Your Windows: You should update your Windows operating system regularly. Then there is less chance for problems to arise as well as extensive repairs.

3. Connectivity Issues via Networks
If the connectivity is a problem via networks, confirm that your internet is stable. A poor connection may fail to allow file downloads, which you will need to complete the work for DISM.
4. Source to fix it
In case the tool does not repair the image after its default settings, you have to provide a valid source to repair. You can do it with a Windows installation DVD or USB drive. Then, you have to point DISM in the right direction in which the files of Windows are.
