How to fix corrupted files in windows 10
One of the most troubling problems for users of Windows 10 is file corruption. Corrupted files can result in lost data, programs that refuse to open, or even complete system failure. Understanding what causes file corruption, how to detect it, and most importantly, how to fix it, is essential for maintaining a healthy and functional computer.
File corruption occurs when a file’s data is altered unintentionally, making it unreadable or unusable by the program that created it. Corruption can affect individual files, entire folders, or system files that Windows depends on to function correctly.
Common Causes of File Corruption
Several factors can contribute to file corruption, including:
Sudden power outages
Improper system shutdowns
Software crashes
Malware and viruses
Hardware failures (especially hard drives and RAM)
Faulty sectors on storage drives
Interrupted file transfers
Aging hard drives or SSDs
By understanding the root causes, users can take steps to prevent future issues and address existing ones more effectively.
Signs of File Corruption
Corrupted files manifest in various ways. Some common symptoms include:
Files refusing to open or displaying error messages
Programs crashing during launch or operation
System lag, freezes, or unexpected restarts
Blue Screen of Death (BSOD)
Missing or unreadable documents
Unusual file behavior (e.g., incorrect icons, incomplete data)
When these signs appear, it’s a strong indication that file corruption may be present.
Methods to Fix Corrupted Files in Windows 10
Windows 10 offers several built-in tools that allow users to scan for and repair corrupted files. Below are detailed instructions for using these tools and methods.
Method 1: Run the System File Checker (SFC)
The System File Checker is a Windows utility that scans for and repairs corrupted system files.
Steps:
Press Windows + S and type Command Prompt.
Right-click Command Prompt and select Run as administrator.
In the Command Prompt window, type the following command and press Enter:
bash
CopyEdit
sfc /scannow
This command initiates a system-wide scan. If corrupted system files are found, SFC will attempt to repair them automatically.
The process can take several minutes. Once complete, the tool will display a message indicating whether corruption was found and fixed.
Method 2: Use DISM (Deployment Imaging Service and Management Tool)
If SFC cannot fix the problem, DISM is the next line of defense. DISM repairs the Windows image and enables SFC to perform successfully.
Steps:
Open Command Prompt as an administrator.
Type the following command and press Enter:
swift
CopyEdit
DISM /Online /Cleanup-Image /RestoreHealth
DISM will scan and repair any corruption in the Windows image. This process may take some time, depending on system performance and the level of corruption.
Once finished, re-run the SFC scan to verify that all files are now fixed.
Method 3: Perform a Check Disk Scan (CHKDSK)
CHKDSK scans the entire drive for bad sectors and file system errors, repairing them when possible.
Steps:
Open Command Prompt as administrator.
Type the following command and press Enter:
bash
CopyEdit
chkdsk C: /f /r /x
/f attempts to fix errors.
/r locates bad sectors and recovers readable information.
/x forces the volume to dismount before the scan.
You may be asked to schedule a scan for the next restart. Type Y and press Enter, then reboot your computer. CHKDSK will run during startup.
Method 4: Restore Previous Versions
If you have File History or System Protection enabled, you may be able to recover uncorrupted versions of files.
Steps:
Navigate to the folder containing the corrupted file.
Right-click the file and select Restore previous versions.
A list of available versions will appear.
Select a version and click Restore.
This feature relies on restore points or backups, so availability may vary.
Method 5: Use Windows File Recovery Tool
Panda Repair
File corruption in Windows 10 can lead to a range of frustrating problems, from programs crashing to inaccessible documents and system errors. Panda Repair is a powerful tool designed to tackle these issues head-on, offering a reliable way to detect and fix corrupted files quickly and safely.
Whether the corruption is caused by a sudden shutdown, software conflict, malware attack, or bad sectors on a hard drive, Panda Repair uses advanced scanning algorithms to identify damaged files at their source. Once detected, it attempts to restore the file's original structure or recover as much usable data as possible—helping you avoid data loss and restore system stability.

Method 6: Perform a System Restore
System Restore rolls your system back to a previous point in time, potentially restoring corrupted system files to a working state.
Steps:
Press Windows + S and search for System Restore.
Select Create a restore point from the list.
In the System Properties window, click System Restore.
Choose a restore point created before the corruption began.
Follow the on-screen prompts to complete the process.
Note that this will affect system settings and installed applications but will not delete personal files.
Method 7: Reinstall the Affected Application
If only one specific application is showing corrupted files or refusing to launch, reinstalling it may fix the problem.
Steps:
Press Windows + I to open Settings.
Go to Apps > Apps & features.
Locate the application and click Uninstall.
Reboot your computer.
Reinstall the application from a trusted source.
This is often effective for corrupted program files that are not system-related.
Method 8: Use Third-Party File Repair Tools
Some file types, such as documents, images, or videos, may require third-party utilities for repair. Many developers offer dedicated repair tools for:
Word, Excel, and PowerPoint files
ZIP or RAR archives
JPEG, PNG, or MP4 files
PDF documents
When selecting third-party tools, ensure they are reputable and have positive user feedback to avoid malware or scams.
Preventing File Corruption
Once you’ve fixed the immediate issue, taking proactive steps to avoid future corruption is essential.
Best Practices:
Use a reliable power source: Sudden power loss is a leading cause of file corruption. Use a UPS if possible.
Shut down properly: Avoid hard shutdowns or forced restarts.
Keep software updated: Updates often fix bugs that could lead to file damage.
Run antivirus scans: Malware can corrupt or delete files. Keep your antivirus up to date.
Use Safe Eject for external drives: Always use “Safely Remove Hardware” to avoid interrupting file transfers.
Avoid overfilling your hard drive: Low disk space can cause performance issues and increase risk.
Schedule regular CHKDSK scans: Catch and repair bad sectors before they cause damage.
Back up regularly: Use File History, OneDrive, or third-party backup tools to keep your data safe.
Backup Strategy Recommendations
Even the best repair methods cannot guarantee complete file recovery. A consistent backup strategy ensures you’ll always have a fallback in case something goes wrong.
Daily or weekly backups of important documents.
Cloud storage for essential personal files.
System image backups using Windows Backup and Restore or third-party software.
Redundancy is your ally. Multiple backup sources—local and cloud-based—offer the greatest protection.
