Summary: What is DISM in Windows OS and How to Use `/healthcheck` and `/restorehealth` to refresh the Windows OS
DISM (Deployment Image Servicing and Management) is a command-line tool integrated into the Windows operating system. It is primarily utilized for servicing and managing Windows images, including offline and online images. DISM allows system administrators and advanced users to perform various tasks such as repairing corrupt or missing system files, deploying Windows updates, and modifying Windows operating system configurations.
To refresh the Windows OS using DISM, there are two key parameters that can be utilized: `/healthcheck` and `/restorehealth`.
# /healthcheck Parameter:
The `/healthcheck` parameter is used to verify the health of the Windows image. It checks for any corruption or missing files that might be causing issues with the operating system. Performing a health check can help identify potential problems, allowing users to take corrective measures.
To use the `/healthcheck` parameter, follow these steps:
1. Open the Command Prompt with administrative privileges.
2. Type the following command: `DISM /Online /Cleanup-Image /CheckHealth`
3. Press Enter.
4. DISM will start scanning the Windows image for any issues and display the results.
5. Interpret the output to determine if any corruption or problems were detected.
# /restorehealth Parameter:
The `/restorehealth` parameter is used to repair or restore the Windows image from a known good source. It utilizes Windows Update or an installation media (such as a DVD or USB drive) as the source for the repair files. It can fix various issues, including missing or corrupted system files.
To use the `/restorehealth` parameter, follow these steps:
1. Open the Command Prompt with administrative privileges.
2. Type the following command: `DISM /Online /Cleanup-Image /RestoreHealth`
3. Press Enter.
4. DISM will start the repair process, accessing the online Windows update service or the specified installation media to retrieve the necessary files.
5. Note that the process may take some time, depending on the speed of the internet connection and the size of the downloaded files.
6. Once completed, DISM will display the repair progress and the outcome.
It's important to note that utilizing DISM commands requires administrative privileges and an active internet connection for online repairs.
