The Deployment Image Servicing and Management tool is an advanced, easy way to diagnose and repair common problems in Windows 11. Many of these issues, such as slow performance, boot errors, and random system crashes, are too often caused by file corruption, which this tool can fix easily.

If “Command Tool” sounds daunting, don’t be afraid—most of us are. It is not that hard. Just follow these easy steps and with the given commands, you will be well on your way to resolving these issues in no time.

How to Check and Fix Your Filesystem

A disk check must be performed before running the DISM repair to identify any file system issues and correct them. Failure to do so could render any DISM and SFC repairs subsequently irrelevant because the corruption would simply recur from unresolved file system issues. As one forum member, ericpeacock79, pointed out correctly, “the file corruption will just return” if this step is skipped.

1. Open Command Prompt as an Administrator

First, click the Start button, and in the search space provided below the Start button, type in "Command Prompt". Once you’ve located Command Prompt in the results area, right-click on it and select "Run as administrator". This will be required for all of the DISM and SFC commands you’re going to run in the steps below.

2. Run the Command chkdsk and Start It

In the administrator Command Prompt, type "chkdsk c: /f /r," and then press Enter. It may prompt that you’ll need to schedule a disk check next time when the computer restarts; just type "Y” and Enter to confirm. Next time when you boot your computer, the system will run a disk check automatically during boot.

3. Allow the Disk Check to Run Without Interruption

When your computer restarts, you may be given the option to bypass the disk check if you need to access Windows quickly. However, if time permits, it’s crucial to let the disk check proceed without interference. Interrupting this process could result in significant file system corruption, potentially causing more harm than good. Therefore, it’s best to allow the check to complete its course undisturbed.

Resolving Windows 11 Image Issues Using the DISM Tool

The DISM tool is an excellent choice for thoroughly scanning system files to identify and repair any corrupted or missing data. If you’re encountering problems with your operating system setup, DISM can address these issues effectively. For additional file repairs, especially when dealing with specific OS setup complications, the SFC tool becomes a valuable companion to DISM. Together, they provide a comprehensive solution to restore your Windows 11 system to optimal health.

1. Assess the System’s Health

To begin, input the command: "DISM /Online /Cleanup-Image /CheckHealth" and press Enter. This command instructs the DISM tool to perform a quick scan of your system, checking for any signs of corrupted files or data that may need attention.

2. Looking for a More Thorough Examination?

If a deeper analysis is required, the ScanHealth option is your next step. Execute the command “DISM /Online /Cleanup-Image /ScanHealth” and press Enter. Though this process may take a bit longer, it will meticulously search your system to pinpoint specific file corruptions that need addressing.

3. Ready to Fix!

Now that the corrupted files have been identified, begin restoring them by entering the command "DISM /Online /Cleanup-Image /RestoreHealth" and hitting Enter. Much like the ScanHealth process, this may take a little while to complete. You might see the progress bar halt for a moment on its own; it’s all right. It is working hard in the background, downloading and replacing corrupted files, so patience is key here.

Performing a Full-System Check of Files in Windows 11

If you have problems which are part of the setup of Windows itself, or if you want to be sure that everything is okay after the DISM tool fixes any issues, then your best bet is the System File Checker. This tool gives you further peace of mind by checking and repairing system files so that your operating system can run smoothly.

Initiate the System Scan

Now that you’ve tackled the previous steps, it’s time to run a full system scan. Open Command Prompt with administrator privileges and enter the command “SFC /scannow,” then press Enter. This will perform a thorough scan of your system, repairing any corrupted files using your newly restored local image files. If any errors are detected, don’t hesitate to run the scan multiple times, as SFC /scannow is known to occasionally miss issues on the first pass.
