System File Checker
(SFC) Tool
|
| |
| The System File
Checker is a tool supplied by Microsoft that scans
for missing or corrupt system files. If any problems
are detected it will attempt to repair the corrupt
or missing system files by repairing or replacing
them with a good copy. |
| |
| Using System File
Checker |
| 1 - System
File Checker runs from an elevated command prompt.
To open the command prompt, click Start > All
Programs > Accessories. Right click on Command
Prompt then left click Run As Administrator.
Depending on the system it may be necessary to enter
a password or verify the UAC confirmation prompt. |
 |
| 2 - At the
elevated command prompt, type [ sfc /scannow ] and
press the [ Enter ] key. The system scan will begin. |
 |
| 3 - During
the course of the scan, all protected system files
will be scanned. Incorrect or corrupt versions will
be replaced or repaired if possible. |
 |
| 4 - If you
want to see what actually went on behind the scenes
while System File Checker was running, there is a
log available at C:\Windows\Logs\CBS\CBS.txt that
details each step of the process. If SFC was unable
to replace or repair any problems, this file can be
used in conjunction with a manual repair from the
command prompt. If you do find yourself in a manual
repair situation, write me and I'll explain how to
go about performing the repair, but it's beyond the
scope of this tutorial. |

- Important Information -
The Elder Geek sites contain many articles and suggestions for
modifying the Windows operating system. I've tried these
tweaks and tips on many systems. Sometimes they work,
sometimes not. The point is, ensure you have a current,
tested backup of all system and data files and understand
how to restore the system in case something goes very wrong.
You can still yell at me, but I assume no responsibility for
your actions and use of the information and disclaim any
legal responsibility for any consequences of such actions. |
