System File Checker May Not Replace Older Files

When you run System File Checker using the default settings, you may not be prompted to replace older or deleted files.

This behavior can occur if you have not enabled the following settings:

• Check for changed files
• Check for deleted files

If these settings are not enabled, System File Checker only appends the Sfclog.txt file, and does not prompt you to make changes.

To resolve this issue, use the following steps:

1. Click Start, click Run, type sfc.exe in the Open box, and then click OK.
2. Click Settings, and then click the Check For Changed Files and Check For Deleted Files check boxes to select them.
3. Click OK, click Scan Files For Errors, and then click Start.

By default, System File Checker starts with those settings disabled. After you enable those settings, they remain the default settings.
