The SFC will not overwrite existing hotfixes or Service Pack files.
SFC in Windows XP will look in Windows\ServicePackFiles\i386 for updated files.
The XP CD is only required for core files that have not been changed by subsequent
Service Pack updates.
As long as you did not delete the Windows directory that contains the
downloaded Service Pack files, SFC will use the updated SP files when
running SFC.
MS-MVP Kelly Theriot has the explanation you are looking for.
Visit
http://www.kellys-korner-xp.com/xp_s.htm and scroll way
down to "SP1 - System File Checker".
1. Go to Start > Run and type: CMD , and hit enter.
2. In the Command Prompt window type: SFC /SCANNOW
and hit enter. Have your Windows XP CD available.
After running SFC:
Go to Start > Programs > Accessories > System Tools >
System Information > View > System History

| when running this does it overwrite the updated system files with the older
| ones from the CD? How do I run SFC and keep the updated files? The files on
| the CD are pre-SP1 and thats not good.
