Windows 10 users often experience crashes, freezes, error codes, and symptoms of software malfunctions. These may be due to corrupted system files. This guide includes simple methods to help you understand how to fix corrupted files on Windows 10. All of the methods are designed to be easy enough for a beginner to follow.
So that you may understand how to locate and fix corrupted files, ilmydunya.com is providing this guide. Although corrupted files may sound technical, with a strict order, the repair is simple and easy.
There are many reasons why a file may be corrupted. A file may be corrupted if your computer loses electricity or is forced to shutdown during an update. Corrupted files may also be caused by a virus or malware infection. Errors on your computer’s hard drive may also cause file corruption, along with poorly executed or incomplete Windows updates. All of these causes may result in Windows 10 experiencing lagging, instability, or the inability to run certain programs and applications.
Windows 10 does include tools to help you repair corrupted files. These include SFC, DISM, and CHKDSK. All of these tools are designed to repair corrupted files by using their built-in capabilities to scan for damaged files.
What Are Corrupted Files in Windows 10?
A corrupted file makes it unable to finish any task. Windows or an application loses the ability to read the corrupted file. Many corrupted files are unwilling to show their contents.
Corrupted files fall into two general categories:
1. Corrupted Personal Files
These include:
- Word documents
- Excel spreadsheets
- Photos and videos
- PDF documents
- Downloaded documents
- ZIP folders
Examples include an unopenable Word document or a photo displaying an error. This is typically a personal file corruption issue.
2. Corrupted System Files
These include important Windows files that support your computer’s functionality. Serious issues such as the following may arise:
- Windows startup issues
- Blue screen problems
- Slow performance
- Failed Windows Updates
- Unresponsive apps
- Missing DLL issues
- Unexpected computer restarts
This guide shows how to repair corrupted system files in Windows 10. Some techniques can be employed to fix general file problems too.
Signs of Corrupted Files in Windows 10
Prior to fixing a problem, it helps to identify the symptoms. Corrupted files exhibit various problems, depending on the type.
These include:
- Windows 10 suddenly becoming unresponsive
- Automated launching and closing of applications
- Missing files error when apps are opened
- Repeated failures of Windows Update
- The Blue Screen of Death
- Frequent crashes of File Explorer
- Unopenable files
- Frequent system hangs
- Delayed startup
- Integrity error responses when using the Command Prompt
These symptoms can also present when there is a virus, driver issues, or hard drive problems. This is why you must carefully follow a troubleshooting framework.
How to Fix Corrupted Files Windows 10 with SFC Scan
The System File Checker, or SFC, is simple and effective. SFC scans protected Windows system files. If there are system files that SFC can replace, then SFC replaces those system files with the correct version. Microsoft also recommends using the System File Checker to replace missing or corrupted system files.
Step 1. Start the Command as Administrator
Finding the Start Menu and typing cmd or Command Prompt. The next step is to right click the Command Prompt to Run as Administrator. If a prompt appears to ask for permission, click Yes.
Protected system files won’t be repaired without you being in Administrator mode.
Step 2. Execute the SFC Command
Type the following exactly as
sfc /scannow
Finally, press Enter.
Windows will begin the system file scan. This can take several minutes. The Command Prompt window must remain open.
Step 3. Reading the SFC Results
The results of the scan can yield 1 of several results.
“Windows Resource Protection did not find any integrity violations”
If this result is found, SFC found no corrupted system files. The cause of your issue could be drivers, malware, or problems with your disk.
“Windows Resource Protection found corrupt files and successfully repaired them”
This is a positive result. Windows repaired the corrupted system files, and you should do a reboot of your PC.
“Windows Resource Protection found corrupt files but was unable to fix some of them”
When you receive this error message, it simply indicates that SFC (System File Checker) has discovered issues and was unable to resolve all of them. Therefore, the next step is to execute the DISM command.
How to Repair Corrupted Files on Windows 10 Using DISM
When SFC is unable to resolve all the issues, the next tool to use is DISM (Deployment Image Servicing and Management). To describe it simply, DISM is a tool that repairs the Windows System Image, which SFC uses to restore those files.
According to Microsoft documentation, DISM can correct issues with Windows Images, and the /Restore Health option allows you to repair a Windows Image from the available repair sources.
Step 1: Launch Command Prompt as Administrator
As in the first steps, you will be launching Command Prompt as Administrator
- Select the Start option.
- Then, search the command.
- Then, right-click on Command Prompt.
- Then, select the Run as Administrator option.
Step 2: Enter the DISM Restore Health Command
Then, you will be entering the following command:
DISM /Online /Cleanup-Image /RestoreHealth
Then, you will select Enter.
This command will allow the system to check the Windows image and repair issues. As this could take some time to start and finish, you will need to be patient and ensure that you have a stable internet connection, as Windows may need to download repair files.
Step 3: Re-run the SFC Command
Having DISM complete the command, it will be necessary to execute the following command:
sfc /scannow
Completing this SFC command is essential as DISM repairs the source image, and SFC can utilize that repaired image to correct the issues.
Using Check Disk CHKDSK to Repair Damaged Files on Windows 10
File corruption occasionally happens because of SSD or HDD issues. Generally, DISM or SFC aren’t sufficient in this instance. You should consider running CHKDSK as it will assist in verifying file system errors on the disk.
Step 1. Launch Command Prompt as Administrator
First, you need to launch the command prompt as the administrator.
Step 2. Enter CHKDSK commands
Deliver the command below:
chkdsk C: /f /rAnd then press the Enter key.
The following is the explanation of the components of the command above:
- C: is your primary Windows drive.
- The /f component works by fixing file system errors.
- The /r component identifies bad sectors and, along with that, it also attempts to recover the information that is read.
Step 3. Perform Computer Restart
In case Windows indicates that the drive is being utilized, it will then make a request if you are interested in scheduling the scans for the next startup. Simply state:
Y
Then go ahead and pres the Enter key, and also restart your device.
It might take a long time CHKDSK to complete all the necessary scans as it is an older hard drive. Ensure you do not switch off your device amid the process.
After completing any necessary computer repairs, it is essential to restart the your computer.
While this, on the surface, may appear to be a lack of information, it is essential to restart after running any of sfc, dism or CHKDSK.
After the restart, check if the issue you are had is resolved, and that any problematic file, application, or system component is now functioning.
Update Your Windows Operating System
Updating Windows may resolve the issue by reinstalling any offending components or files that may be missing.
The steps are below:
- Open your settings.
- Head to update and security.
- Click Windows Update.
- Choose to Check for updates.
- Apply all offered updates.
Restart Your PC
Some corruption problems occur if updates fail or get interrupted. Updating Windows can install, repair, or replace programs that Windows needs.
Scan for Malware and Viruses
Malware can damage files and system settings, and even prevent Windows from repairing itself. Therefore, you should always scan for malware after repairing corrupted files.
Use Windows Security
These options will get you there:
- Open Start.
- Windows Security, and if not found, search for it.
- “Virus & threat protection”
- “Scan options”
- “Full scan”
- “Scan now”
Why a Malware Scan Matters
It is a smart move because if you repair corrupted files, but malware is still on your system, the system corruption can happen again.
Use Safe Mode to Fix Corrupted Files
Normal Windows can have services, apps, and drivers that prevent you from using repair tools, and therefore Safe Mode can be used to solve that. Safe Mode uses only basic Windows services and drivers, and the system can be repaired more easily.
How to Start Windows 10 in Safe Mode
Using Safe Mode with the minimum of drivers can be done by using the following steps:
- Press Windows + I to open Settings.
- Go to Update & Security.
- Recovery.
- Advanced startup: Restart now.
- Restart to Safe Mode by choosing the following “Troubleshoot”, “Advanced options”, “Startup Settings”, and finally press Restart.
Run “sfc /scannow” in Safe Mode
You can run the DISM tool too if you require.
Repairing Corrupt Files with System Restore
If you notice corruption with new system updates, you can repair the corruption with System Restore. System Restore resets the settings and files of the system to a previous state. When running a System Restore, no personal files will be deleted. Keep in mind that additional programs and drivers will be deleted.
Restoring your system is a simple process:
- Press Windows + S simultaneously.
- Type in “Create a restore point”.
- Click Create a restore point.
- Click System Restore.
- Choose a restore point.
- Click Next, then Finish.
Once the System Restore has completed, the computer will restart, and the newer settings and files will be removed from the system.
Using System Restore is a good option when corruption starts after the new updates to your drivers, programs, or Windows updates.
Use Startup Repair If Windows 10 Does Not Boot
When Windows 10 starts to malfunction and crashes, a tool called Startup Repair can be useful.
Using Startup Repair is a quick process:
- Start the computer.
- Perform a forced shutdown of the PC by holding the power button, while Windows is starting to load.
- This forced shutdown must be performed 2-3 times to access Windows Recovery Mode.
- Click on Advanced options.
- Click on Troubleshoot.
- Select Advanced Options and click on Startup Repair.
During this process, Windows will scan the startup files and repair the boot issues. This option is useful when corrupted files are preventing Windows from loading.
Reset Windows 10 Without Losing Personal Files
If the Windows issues you’ve been experiencing are not resolved after trying SFC, DISM, CHKDSK, and Safe Mode, you may be left with the choice to reset Windows 10.
Resetting Windows 10 also provides the option to keep personal files, but downloaded programs and settings will be lost. The reset process is the following:
- Go to Settings.
- Select Update & Security.
- Click Recovery.
- Under Reset this PC, select Get started.
- Choose to Keep my files.
Follow the instructions displayed on the screen.
Make sure to backup your important data on an external drive or the cloud before performing a reset.
Repair Corrupted Files
When your personal files become corrupted, it’s unlikely that system repair tools will resolve the issue. For example, if there is corruption in a Word file or in a photo, then other specific steps will be needed.
Open with Other Applications
It is possible the file is not being fully corrupted and that the application is failing to read it. If this is the case, you can try opening the file in other applications that support the file type.
Examples:
- You can open Word files using Google Docs.
- You can open a photo using a different photo viewer.
- You can open a video using the VLC Media Player.
- You can use other archive tools to extract a ZIP file.
Original File Recovery
While not guaranteed, it is possible that older versions of your files exist if File History or restore points were enabled.
To view older files or folders, right-click and choose:
Restore previous versions
Then select the desired older version.
Check Your Backups
- OneDrive
- Google Drive
- Hard drive
- USB Drive
- Recycle Bin
Many people forget that they might have saved an older version.
Best Order to Repair Corrupted Files in Windows 10
To get the best results, it is important to follow the recommended steps in the correct order.
Step 1: Restart your PC
Normally the first step to take is to restart your PC in case small temporary errors resolve on their own.
