You run the System File Checker when you are experiencing problems with
Windows that you suspect may be due to system files that have been changed
or deleted.

You perform a repair install when you are experiencing problems with Windows
that cannot be solved in any other way.

thanks, I understand , but not fully
do you can tell me some example of each situation we must use one of them
tools
 
To add to what Ted wrote, when running the System Files Checker (sfc.exe)
chances are really slim that any of your data will be toasted. Using sfc is
like using defrag or chkdsk, no big deal. Just system maintenance.

[[If System File Checker discovers that a protected file has been
overwritten, it retrieves the correct version of the file from the cache
folder (%Systemroot%\System32\Dllcache) or the Windows installation source
files, and then replaces the incorrect file. System File Checker also checks
and repopulates the cache folder.]]

The Dllcache folder contains Windows File Protection backup files.

A repair install can be a big deal. With a repair install you stand a much
better chance of toasting your data.

[[Warning!
Should you do a repair install; and is it the best choice?
A Repair Install is not foolproof, and should not be considered the cure-all
fix for non-boot situations. Check the link below for an option for
recovering from a non-boot event. ]]

What Ted was saying was, try SFC first, and if that doesn't work do a
repair install, but the latter should be a last resort. Maybe you should
tell *us* what problems you're having.

Any of these (and anything else that writes to disk, which includes
Windows itself) can be a problem if the hardware's flaky, hard drive
is failing, or file system is messed up. Which are three likely
causes of general PC distress that may suggest a re-install.

The more is written, the worse the risk - so I'd consider SFC and
ChkDsk to be lower risk than Defrag and a re-install.

Yep.
