System File Checker (SFC) is a built-in tool in Windows that scans for corrupted system files and replaces them with a cached copy. However, there are times when SFC may fail to restore a file, leaving your system vulnerable to errors and crashes. In such cases, running System Restore can help resolve the issue.

Why SFC may fail to restore a file

SFC may fail to restore a file due to various reasons, including:

1. The file is in use by a running process

2. The file is a system file that cannot be replaced while Windows is running

3. The file is corrupted beyond repair

4. The cached copy of the file is also corrupted

When SFC fails to restore a file, it may display an error message such as “Windows Resource Protection found corrupt files but was unable to fix some of them.”

How System Restore can help

System Restore is a feature in Windows that allows you to revert your system to a previous state. This can help fix issues caused by system changes, including corrupted files. When you run System Restore, Windows creates a restore point that you can revert to if anything goes wrong.

By restoring your system to a previous state, you can potentially fix any issues that prevented SFC from restoring a file. However, it’s worth noting that System Restore is not always a guaranteed fix, and it may not be able to restore all files.

How to run System Restore

To run System Restore, follow these steps:

1. Go to the Start menu and search for “System Restore”

2. Click on “Create a restore point” to open the System Properties window

3. Click on the “System Restore” button to open the System Restore window

4. Follow the prompts to select a restore point and restore your system

It’s important to note that running System Restore will undo any system changes made after the selected restore point. This includes installed programs, Windows updates, and system settings. Therefore, it’s recommended to create a backup of your important files before running System Restore.

Conclusion

If System File Checker fails to restore a file, running System Restore can potentially fix the issue. However, it’s not always a guaranteed fix, and it may not be able to restore all files. It’s important to create a backup of your important files before running System Restore, as it will undo any system changes made after the selected restore point.
