Hi,

Never performed a sfc scan on my machines. How often should it done, it's pros and cons?

What command should I run?

Thanks.

System File Checker is a tool used to verify that Windows files are in the correct location and at the correct verion lvel.

It's a repair tool, not a maintenance tool, so you should only run it if requested by a technical person who can then analyze the log.

Why do you ask?

Here's how it's done with some more illumination about it.
This may help, run the steps outlined in this tutorial, Option Two, and reboot the system:
SFC /SCANNOW Command - System File Checker

Note   Note
If after 2 runs there are still corrupt files, it won't fix it. I can ask for further help if so.


You may get this result:
Code:
Windows Resource Protection found corrupt files and successfully repaired
them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For
example C:\Windows\Logs\CBS\CBS.log
The system file repair changes will take effect after the next reboot.
Or a message that no integrity violations were found.
Or that Windows Resource Protection found errors it cannot repair, if so rerun the steps above.

As stated SFC does not need to be run unless you have some problem with Windows although it does no harm.
