Can I downgrade from XP PRO to XP Home without losing
files? If so, how?
No. There is no downgrade path. You would have to clean-install
Home.
Why do you want to? Are you aware that Home is a subset of
Professional, and there's no possible advantage to doing so?
There's nothing in Home that's not also in Professional.
The only good reason I can think of for doing this is that you
don't need Professional on this computer, and want its license
for use on another machine.
