How to repair corrupt files in windows 10

​Windows 10 is a powerful and widely used operating system, but like all software, it is susceptible to file corruption. Corrupt files on your PC—whether system files critical for Windows to operate or personal files like documents and media can cause errors, crashes, or even data loss. Knowing how to identify and repair these corrupted files is essential to keep your computer running smoothly.

File corruption means a file’s data has become damaged or altered, making it unusable or causing errors when you try to open it. Corruption can affect:

System files: Crucial Windows operating system files

Program files: Files needed for software applications to function

Personal files: Documents, images, videos, spreadsheets, etc.

Common Causes of File Corruption

Sudden shutdowns or power outages during file saving or system operations

Malware or virus infections

Hardware issues such as failing hard drives, bad sectors, or faulty RAM

Improper system updates or crashes

File system errors due to improper dismounting or unsafe removal of drives

Software conflicts or bugs

Disk write errors or storage device corruption

Signs You Have Corrupted Files

Windows or programs crash or freeze unexpectedly

Error messages like “File is corrupted,” “File cannot be opened,” or “Missing/corrupted system files”

Files failing to open or showing garbled content

Slow system performance or blue screen errors (BSOD)

Missing icons or broken shortcuts

How to Repair Corrupt System Files in Windows 10

System files are the backbone of your operating system. Corrupted system files can cause Windows to behave erratically. Luckily, Windows 10 has built-in tools to scan and repair corrupted system files.

1. Using the System File Checker (SFC)

The System File Checker (SFC) is a command-line tool that scans your system for corrupted or missing system files and repairs them using cached copies stored in Windows.

How to Run SFC

Press Windows key + X, then select Windows Terminal (Admin) or Command Prompt (Admin).

In the command prompt window, type:

bash

CopyEdit

sfc /scannow

Press Enter.

The scan will begin and may take some time (10-20 minutes). Do not close the window.

After the scan, the system will report one of the following:

No integrity violations found — Your system files are intact.

Found corrupt files and repaired them — Problems were fixed.

Found corrupt files but could not fix some — Further steps are needed.

Restart your PC after the process completes.

2. Using the Deployment Image Servicing and Management (DISM) Tool

If SFC can’t fix corrupted files, use DISM to repair the Windows image itself, which SFC uses as a source for repairs.

Steps to Run DISM

Open Command Prompt (Admin) or Windows Terminal (Admin).

Type the following commands one by one and press Enter after each:

swift

CopyEdit

DISM /Online /Cleanup-Image /CheckHealth DISM /Online /Cleanup-Image /ScanHealth DISM /Online /Cleanup-Image /RestoreHealth

The /CheckHealth and /ScanHealth commands check for corruption.

/RestoreHealth attempts to repair the Windows image using Windows Update.

The process may take 15-30 minutes.

After DISM completes, run the sfc /scannow command again to fix any remaining issues.

Restart your computer.

3. Running CHKDSK to Check Disk Integrity

Sometimes corrupted files are due to bad sectors on your hard drive.

To run CHKDSK:

Open Command Prompt (Admin).

Type:

bash

CopyEdit

chkdsk C: /f /r /x

Explanation:

C: is the drive letter; change it if your Windows is installed on another drive.

/f fixes errors.

/r locates bad sectors and recovers readable data.

/x forces the drive to dismount.

You will be prompted to schedule the scan at next reboot. Type Y and restart.

CHKDSK will scan your drive and attempt repairs.

How to Repair Corrupted Personal Files in Windows 10

Corruption can also affect your documents, spreadsheets, photos, and videos. The repair approach depends on the file type.

Repair Corrupted Microsoft Office Files

Use Microsoft Office built-in repair:

Open the Office app (Word, Excel, PowerPoint).

Go to File > Open.

Select the corrupted file.

Click the dropdown arrow on the Open button and choose Open and Repair.

Choose Repair to fix the file or Extract Data if repair fails.

Recover Previous Versions Using File History or Restore Points

If your files are corrupted, you may be able to restore previous versions.

Right-click the corrupted file or folder.

Select Properties.

Go to the Previous Versions tab.

Select an available version and click Restore.

Use Third-Party File Repair Tools
