NOTE: RUN THE CMD PROGRAM AS ADMINISTRATOR
The first command we have on our list is sfc
standing for System File Checker
, is a command that will look into the system protect files and make sure they aren't corrupted or out-of-date, if sfc
does find corrupted files, or files with incorrect versions, it will then replace the files with the current Microsoft up-to date versions. The most basic usage of this command would be sfc /scannow
Oops! sfc found corrupt files, but if you notice sfc was able to repair them.
The second command we have on our list would be dism
, also known as Deployment Image Servicing
, dism does the same thing as sfc but in a more in depth way, by installing, uninstalling, configuring, packing and updating features in a windows image. It will find the version of windows that's on the current computer and compare it to the Microsoft official website version. dism /online /cleanup-image /restorehealth
NOTE: This program takes forever to run, around 30-mins, once this program is finished running it's always a good idea to re-run sfc, to make sure everything is intact.
The last command we have on our list is the chkdsk
, which stands for check disk
is used to check a disk and repair or recover data on a drive. If any sectors are found to be bad, chkdsk will mark it down as "bad".
Now chkdsk ran by itself won't fix any bad sectors, but if we add a flag such as chkdsk /f
, /f meaning /f = Fixes errors on the disk
it will then go into the drive and fix the bad sectors.
Thanks fore reading
