If you own a Windows computer and have ever dealt with performance issues, corrupted files, or unexpected errors, you've probably found yourself looking for a quick and efficient solution. This is where two essential tools come into play: commands DISM y CFS. Although they are not as well known as other features of the operating system, their utility is undisputed when it comes to fixing critical bugs.
In this article you will discover everything you need to know about these commands, from their main uses to how to run them correctly to keep your system in optimal condition. Get ready to learn in depth about these tools that can be the salvation of many Windows users.
What are DISM and SFC commands?
The commands DISM (Deployment Image Servicing and Management) and CFS (System File Checker) are two tools included in Windows that are used to identify and resolve system file problems. Although they share the goal of repairing errors, they work differently and have different specific purposes which makes them complementary.
The command CFS It is mainly used to verify the integrity of system files and repair those that are damaged or missing. In the meantime, DISM It is a more advanced tool that repairs the operating system image, including the underlying structure that supports system files. Both tools are essentials to maintain a healthy operating system.
When to use SFC and DISM?
Knowing when to use each of these commands is key to their effectiveness. In general, users tend to run them first CFS, since its scope is more direct and acts on system files. If problems persist or the command cannot perform the necessary repairs, it is advisable to resort to DISM, which can repair deeper aspects of the system.
For example, if your computer displays frequent error messages related to system files or you detect that critical DLL files are missing, CFS is the perfect tool. On the other hand, if the computer presents more serious problems such as boot failures or a very poor performance, DISM It's the right choice.
How to run SFC on Windows
The command CFS es fast y easy to use. To run it, follow these steps:
- Open the System symbol as administrator. You can search for “cmd” in the Start menu, right-click on the result, and select Run as administrator.
- Type the command
sfc /scannowand press Enter. This command will scan all protected files on the system. - Wait for the process to finish. It may take a few minutes depending on the damage to the files.
Once completed, the system will display a message indicating whether any issues were found and repaired. If there are any corrupted files that could not be repaired, it will be necessary to execute DISM.
How to use DISM to repair Windows
The command DISM It has more complex functionality and requires following a specific order when running it. Its use is detailed below:
- Open the System symbol as administrator.
- Run the command
DISM /Online /Cleanup-Image /CheckHealthto check for system image corruption. - If problems are detected, use
DISM /Online /Cleanup-Image /ScanHealthto perform a more thorough analysis. - Finally, run
DISM /Online /Cleanup-Image /RestoreHealthto attempt to repair the system image. This process may take several minutes or even hours.
If the command RestoreHealth cannot access the files needed to repair the system, you can specify a repair source with the parameter /SourceFor example, if you have a copy of Windows installation on a USB, you can use the command DISM /Online /Cleanup-Image /RestoreHealth /Source:D:/sources/install.wim, where “D:” is the drive letter.
Combine DISM and SFC for complete repair
In many cases, the ideal is to use DISM y CFS jointly. First, execute DISM to repair any problems with the system image and then use CFS to restore protected files.
This approach maximizes your chances of solving any mistake that is affecting the performance of your computer.
Other useful commands: CHKDSK and Netsh
In addition to DISM y CFS, there are other commands you can use to troubleshoot specific on Windows:
- CHKDSK: This command scans the hard drive for bad sectors and file system errors. Run it with
chkdsk C: /f /rfor a complete analysis. - Netsh: Ideal for troubleshooting network issues. For example, you can use
netsh winsock resetto reset the Winsock catalog.
Both commands complement the functions of DISM y CFS, helping to diagnose and repair additional problems.
The commands DISM y CFS are essential tools for any Windows user who wants to keep their operating system in tip-top shape. Whether you're facing performance issues, boot errors, or just want to perform a quick cleanup, preventive maintenanceThese tools offer effective and affordable solutions. By using them correctly, you can ensure that your computer runs optimally and smoothly.
