If some Windows functions aren’t working or Windows crashes, use the System File Checker to scan Windows and restore your files.
The SFC /SCANNOW command scans the integrity of all protected system files and replaces incorrect (corrupted or modified) versions with correct Microsoft versions.
This tutorial will show you how to add a SFC SCANNOW desktop context menu in Windows 10.
The SFC SCANNOW context menu will allow you to quickly run a SFC /SCANNOW command as needed.
When SFC runs in Windows, it logs its actions into the C:\Windows\Logs\CBS\CBS.log file. The SFC scan details log item in the context menu will create a sfcdetails.txt file on your desktop to see only the specific SFC entries with the [SR] tags filtered from the CBS.log for the SFC scan log details.
