sfc /scanfile

Hi,

Using System File Checker (SFC) To Fix Issues

http://blogs.technet.com/b/askcore/archive/2007/12/19/2657136.aspx

Use the System File Checker tool to repair missing or corrupted system files

http://support.microsoft.com/kb/929833/en-us

=============================================================

More information :

Start - type in Search box -  COMMAND   find at top of list -  RIGHT CLICK  -  RUN AS ADMIN

At the ADMIN Command Prompt type in or copy and paste :

sfc /scannow /offbootdir=c:\ /offwindir=c:\windows

=============================================

If the above fails to complete then there are probably disk corruption issues :

Disk issues can get serious very quickly so I would thoroughly check the drive now and

be sure to keep redundant backups of your important data (use several methods). Use

the Advanced Methods and the Manufacturer's Diagnostic Utilities.

Inside Windows - Regular or Safe Mode (repeatedly tap F8 as you boot).

Run checkdisk - schedule it to run at next start and then Apply OK your way out then restart.

For even better and more efficient checking :  <- Advanced Methods.

From the Command Prompt of the Recovery Console (if you have one) or from a Vista/Windows

7 disk - if you do not have a Vista/Windows 7 disk you can borrow a friend's (it needs to be same

32 or 64 bit and they are not copy protected) or make one. Also your System maker will sell the

physical disks cheap since you already own Windows.

chkdsk /f /r

What are the system recovery options in Windows 7?

Go into Setup/Settings (BIOS/CMOS) often F2 as you boot so watch screen as you startup. Set the

boot order to CD/DVD to use Windows disks (Vista or Windows 7 whichever you have installed.)

Remember to set back when done.

**If you need to make repair disks - these help repair Windows not re-install.**Often a these disks will help when the OEM Recovery Disk does not.

Download Windows 7 System Recovery Discs - now charging $9.75 for the ISO

images to make the disks. (These can be made on any computer running XP,

Vista, or Window 7 that has a CD/DVD burner.)
