Windows has built-in tools, known as System File Protection (SFC) and Deployment Image Servicing and Management (DISM), that can help fix installation errors. Here’s a step-by-step guide on how to use these tools:
System File Checker (SFC)
- Open Command Prompt as an administrator.
- Type the following command:
sfc /scannow
- Press Enter. This will scan your system for corrupted system files and replace them with their original values.
The SFC tool checks for and replaces missing or damaged system files. It’s especially useful after a recent installation, update, or virus removal.
Deployment Image Servicing and Management (DISM)
- Open Command Prompt as an administrator.
- Type the following command:
dism /online /cleanup-image /restorehealth
- Press Enter. This will scan your system for corrupted files, remove them if necessary, and repair any damage they may have caused.
DISM is used to restore a clean installation of Windows from a media or other sources. It’s a more advanced tool that can be used after a failed installation or when you’re unable to use SFC due to its complexity.
Troubleshooting Steps
After running the SFC and DISM tools, try the following steps:
- Restart your computer.
- Run the System File Checker (SFC) again:
sfc /scannow
- If the issue persists, run the Deployment Image Servicing and Management (DISM) tool again:
dism /online /cleanup-image /restorehealth
Common Issues and Solutions
- Error 1604: This error occurs when a system file is corrupted or missing. Try running SFC and DISM separately to ensure all system files are replaced.
- Error 1900: This error occurs when you’re unable to install Windows due to a failed installation. Run DISM to restore your computer from a media source, then run SFC again to ensure all system files are updated.
Additional Tips
- Make sure your system is connected to the internet during SFC and DISM scans.
- If you’ve recently installed new software or hardware, try running SFC and DISM after installing them separately to ensure any conflicts are resolved.
- Keep in mind that these tools may not be able to fix all errors, especially if they’re caused by a faulty hardware component.
By following these steps and troubleshooting tips, you should be able to identify and fix Windows installation errors using the System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tools.
