I work for small retail store, our cash register is an XP-based touch screen computer. We are getting a message indicating that we have a missing or corrupt "Windows/system32/config/system" file. I realize that this is a common error and it can be fixed by inserting the XP installation CD and running a repair but this unit does not, nor has it ever had a CD drive. We've considered purchasing an external USB drive and running the CD but since we can't open Windows to install the drivers for the external drive I'm not sure this would work. This unit really only has USB ports, can anyone think of any solutions to this problem?
Thank You
