Replacing windows 8.1 File

So i started to run CMD to scan Corrupted files.... and i have some Corrupted files that needs to be fix, just by replacing all the system files, so can my Windows 8.1 bootable DVD REPLACE the system files without changing/deleting my stuff?   &

Hi there,

Which command did you run? Did you run CHKDSK?

And depending on your issue, your Windows 8.1 disk should be able to fix the issue, yes. (By replacing corrupted files) But do not run the Windows installation again, use the special "Repair" features that come with the disk.

thanks just click on the repair disk, and my stuff won't go away. right?
and yes i did run the command.

Hi there,

Note that CHKDSK doesn't look for corrupted files, it checks your hard disk for bad sectors.
IF you decide to use it, use this command: chkdsk /F /R    (This will also actually "repair" the bad sectors by marking them, so your OS won't use those sectors any more)
Don't think this applies to your situation though.

Anyway, how do you know that you have corrupted system files anyway? Do you get an error? If so, do you mind posting a screenshot of the error, and describe more about it. (E.g. When does/did it pop-up?)

neh a full repair is better.
