The usual choice for damaged repair files of Windows is to run the command sfc /scannow. But it is not your only solution because the SFFCix application also comes into play.
But let's get them from scratch. SFC, which means System File Checker, scans all protected system files by searching for corrupted files, and finds anyone trying to replace it by copying a cached file from the system32 \ dllcache file to the location of the corrupted file.
This method works other times and others do not. For example, if the saved copy is already corrupted, then the repair will not succeed.
And so you will find yourself in the awkward position of receiving the message "Windows Resource Protection found corrupt files but was unable to fix some of them".
As your first move it makes sense to use the solution suggested by Microsoft, but if it does not work then you better look to his side SFCFix. This program is open source, free, portable and compatible with all recent versions of Windows.
The website of the prolettertos doesn't reveal much about how the program works and how it accomplishes what the sfc command failed to do. It only states that it “uses an advanced algorithm search to find and replace damaged or missing system file”. In one another website, it is revealed that it is done by using fragmented file keys. However, it certainly uses the CBS.log file created by the Windows sfc / scannow command.
Το πρόγραμμα είναι εύκολο στη χρήση, αλλά καλό θα ήταν να είστε σχετικά προσεκτικοί. Πρώτα απ ‘όλα, θα πρέπει να είστε σίγουροι ότι δεν υπάρχει κακόβουλο software on your system, that the source of the damage was not a malware attack.
Secondly, you may want to back up your system in case you need to restore Windows to their current state (even with corrupted files) if something goes wrong while executing the following commands.
Before running SFCFix, run sfc / scannow as SFCFix uses the log file created by sfc.
1.> Press the Windows key and in the “Search programs and files” field type cmd.exe, right click on the result and select “Run as administrator” to open a line commands with administrator privileges.
2.> Type sfc / scannow and press enter.
3.> The process scans all protected system files and tries to repair the corrupted files.
4.> Once the process is complete, go to the folder where you saved SFCFix, type SFCFix and press enter.
A full scan can last from 15 minutes to 30 minutes, depending on various factors. The program tells you if the scan will take longer than the estimated time of 15 minutes, so you know how long you have to wait.
The program opens a txt document after scanning with the scan results. It gives you the full path of each corrupted file and has been successfully repaired by SFCFix.
Since it is unclear how the program repairs corrupted files, it is suggested that you take preventive measures before running it on a Windows machine.
