Are you referring to a Repair Install? If so, this page should be

I ask because the term "recovery install" is not the one normally used
and it is unclear what you mean by that. Furthermore, your Subject Line
contains the term "clean install."
Finally, are you referring to a Dell XP Home reinstallation CD or a Dell
recovery CD (for a specific model)? If you are referring to the former,
it is capable of performing both a Repair Install (which should keep
your apps and data intact) or a Clean Install.
I am not too familiar with Dell recovery CDs. Typically, they return the
PC to its condition when it left the factory (which would be like wiping
the CD and performing a Clean Install)
Good luck!
P.S., What specific issues are you experiencing with this particular PC?
Depending on what they are, there may be a far quicker solution than a
Repair or Clean Install.
