Several months ago I bought a copy of XP Home.

Now, as people are aware, Microsoft, in its fight against piracy, requires you to register the license numbers of their Windows products.
Okay, fair enough.

But, what happens if I decide to completely rebuild my hard drive (including removing Windows entirely) or if I purchase a new computer? I have already registered my license, so presumably if I want to reinstall the same legitimately acquired software on either this machine or if I install it on a new one I'll get some kind of message stating that the license is already in use.

Does anyone know anything about this? Would I need to contact Microsoft and demonstrate proof of purchase?

I have this nasty feeling I could be asking a self-evident question or that I might be experiencing a "blonde moment." I have a bad cold which is seriously affecting my ability to think clearly
