Hello George :smileyhappy:

 

Are you thinking of

1. System file check

or

2. a "Repair" of XP?   

 

1.  System File check does just that.  It checks all system files and replaces any that are missing

Put your XP CD in the drive

Start/Run  and type in

sfc /scannow  (there is a space before /)

OK

 

2. A Repair is used to replace missing or corrupted system files and is sometimes referred to as an "over the top" install. 

Here is some information for you.

 

A repair won't lose any data, other than Service Pack (if not on CD), any Windows Updates and unsigned drivers, which will need to be re-installed afterwards.
Stay offline to do a repair and do not go online again without a firewall enabled. After repairing XP, install Service Pack (if necessary), firewall and then you must install all Critical Updates next.

 

How to Repair XP
Boot up with the XP CD in the drive and let Setup run. Go past the first "R" repair option by pressing Enter just as if you're doing a clean install and you'll eventually come to an option to "Repair an existing installation". Select this one.
