The PC is a dell and had XP Home installed and, of course, no OS CD.
I have a genuine XP Pro SP2 CD. Dare I hope?

WinXP is designed to install and upgrade the existing operating system
while simultaneously preserving your applications and data, and
translating as many personalized settings as possible. The process is
designed to be, and normally is, quite painless. That said, things can go
wrong, in a small number of cases. If your data is at all important to
you, back it up before proceeding.
The upgrade from WinXP Home to WinXP Pro, in particular, almost always
goes smoothly, as both operating systems use the same kernel.
However, do you really need to upgrade? The WinXP Home and WinXP Pro
versions are _identical_ when it comes to performance, stability, and
device driver and software application compatibility, but are intended to
meet different functionality, networking, security, and ease-of-use needs,
in different environments. The most significant differences are that
WinXP Pro allows up to 10 simultaneous inbound network connections while
WinXP Home only allows only 5, WinXP Pro is designed to join a Microsoft
domain while WinXP Home cannot, and only WinXP Pro supports file
encryption and IIS. (Oh, and WinXP Pro usually costs roughly $100 USD more
than WinXP Home.)

One more thing - XP Pro has features you may not really want the user to
have.
For one client, I specifically decided for XP Home and against XP Pro
because XP Pro has encryption built-in, and Home does not. That client was
having issues that could potentially (in fact, likely) have led to
encryption being invoked inappropriately, then the accounts changed... which
would have blocked access to the encrypted data.
I was certain that I would have been called to try to recover this
permanently lost data. I was also certain that I didn't want to find out
the effects of encrypting the entire drive and then damaging the accounts.
This was easy to prevent by simply not using Pro.
