More information, the XP installed was XP Professional

You just need to upgrade to SP3.

I got the SP2 CD on hand only. Can I use the CD to do the same?
Besides, will your suggested action erase all data files now stored

No. It will simply upgrade the OS to the next level, leaving your files
alone.
