re-run windows setup to refresh XP OS on IBM 2681C8U

[geercom]

Hi Thinkpad Fans, Techs, and Users,

I have the above system (subject line) and the product recovery CDs (four of them) labeled P/N 01R6473. I can't seem to figure out how to simply rerun Windows setup to refresh the Windows install.

I want to do this without disturbing Service Pack 3, current software, settings, etc, you know what I mean. But for the assumption that I am bound to using the Recovery CDs for the process or else to not have this option, I would know what to do.

What is the simplest way to do this with this setup?
