If your Windows 10 installation becomes corrupted, leading to issues like system crashes, failed updates, or missing files, you’ll need to take action to restore it to a healthy state. Here are several methods you can try to repair a corrupted Windows 10 install and fix corrupted files:
Use the SFC Tool
The System File Checker (SFC) is a built-in Windows tool that can scan for and repair corrupted system files. To use it:
Open an elevated Command Prompt or PowerShell window
Run the command sfc /scannow
If any corrupted files are found, SFC will attempt to repair them
If SFC finds issues but can’t fix them, proceed to the next step.
Use the DISM Tool
The Deployment Image Servicing and Management (DISM) tool can help repair a corrupted Windows image. To use it:
Open an elevated Command Prompt or PowerShell window
Run the command DISM /Online /Cleanup-Image /RestoreHealth
This will download and replace corrupted system files from a known good source
If DISM is unable to restore health, you may need to provide a source location for the files, such as a Windows 10 installation ISO.
Perform a System Restore
If you have System Restore enabled, you can roll back your system to a previous restore point before the corruption occurred. To do this:
Open the System Properties window (search for “restore point”)
Click “System Restore” and follow the wizard to select a restore point
This will revert your system files and settings to the chosen restore point
Keep in mind that a System Restore will not affect your personal files, but it may remove recently installed programs or drivers.
Reset Your Windows 10 Installation
As a last resort, you can reset your Windows 10 installation while keeping your personal files. This essentially reinstalls Windows 10 while preserving your data. To do this:
Open the Settings app and go to “Update & Security” > “Recovery”
Click “Get started” under “Reset this PC”
Choose “Keep my files” and follow the prompts to reset your PC
This will reinstall a fresh copy of Windows 10 while keeping your personal files, but you’ll need to reinstall your programs and drivers.
