The Dell tech was mistaken when you were referred to Microsoft.
Your version of Windows is OEM.
That means it is a Dell product and as part of that Dell has agreed
that no support comes from Microsoft.
Whatever support Dell provides is spelled out in your warranty with
Dell.
You already stated you are using the Dell CD.
Did that CD come with that Dell computer?
Have you made any changes to the computer?
Normally on a Dell you do not need to enter the Product Key when
installing Windows?
Is the motherboard original?
Any other changes?
Are you using the correct Product Key?
The key should be on a sticker affixed to the computer.
Look very closely.
Sometimes 0-O, I-1, G-6, S-5 and others look alike.
Have someone else try, sometimes another set of eyes and fingers can
get it.

I want to reinstall windows XP Home because of error messages I am
getting when I start up and shut down the laptop. I also think I have
a virus or something because my home page keeps getting changed. So I
thought a reinstall would cure what ails me. When I use the Dell
provided reinstallation CD, I get prompted for a Product Key, which I
enter, but I get an error message saying the the code is invalid. I
called Dell and they were not able to even suggest any help other than
to call Microsoft.
