Place the Win XP CD in the CD drive.
When Autoplay starts just click the X and close it.
Click Start button, select Run and type in "sfc /scannow" without the quotes and
the system should scan for missing/corrupt MS OS files and replace them with the
originals found on the disk.
Scans all protected system files and replaces incorrect versions with correct
Microsoft versions.
NOTES -
The Windows File Protection is constantly checking whether important files are
missing or overwritten and restores them if so. Sometimes it can happen that a
file is corrupted anyway, but then one can use the util SFC.EXE with the
/SCANNOW option to do a full scan of the critical files and restore those, which
has become corrupted:
SFC /SCANNOW
Note this operation cannot complete without the install CD. Therefore it is
important to insert the install CD before launching the above command. If the
install path have changed since the original install, then you have to change
the source path so SFC can find the install files.
Note sometimes the WinXP Home will ask for the WinXP Pro CD, but this is not
problem as long the above condition have been met. Though it might require that
one press Retry several times before the System File Checking begins.
