I keep getting an error message that says that files that
require Windows XP to run properly have been changed, and
to load my Windows Service Pack CD. There was only 1 CD
that came with XP when I purchased it, and it says that
it includes the service pack. When I load it into my CD-
ROM, it brings up the initial Windows installation.
HELP!!!
 
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.
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.
Note to see all options for the System File Checker:
SFC /?

If you need to change the install path
You can change where XP/NT expects to find the XP/NT CD, to do this edit the
registry.
[HKEY_LOCAL_MACHINE \SOFTWARE \Microsoft \Windows NT \CurrentVersion]
Sourcepath=D:\I386

[HKEY_LOCAL_MACHINE \SOFTWARE \Microsoft \Windows\CurrentVersion \Setup]
Sourcepath=D:\
