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System File Checker, is a command that will look into the system protect files and make sure they aren't corrupted or out-of-date, if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
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 /restorehealthNOTE: 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.
