I am currently using xp home and have just purchased xp pro. I have a
laptop running xp home and was wondering if I can install xp pro over
xp home or do I have to format the hard drive ??
If your copy of XP Professional is a retail version (Full or Upgrade) you
can do an upgrade. If it's an OEM version, it can't do an upgrade and a
clean installation, formatting the drive, is required.
I really dont want
to lose or back up any of the data currently on this hard drive
If you don't want to lose your data, you should make a backup before doing
even an upgrade. There are no guarantees that it always works perfectly.
However unlikely, it's always possible that something might go wrong and
every gets lost..
Moreover, even if you were to stay with XP Home and do nothing, you should
be making backups regularly. You are always vulnerable to losing everything
due to hard drive crashes, virus attacks, nearby lightning strikes, user
error, theft of the computer, etc. As has often been said, it's not a matter
of whether you wil lose your data, but when.
One more point: are you sure you want to do this? Are you aware that XP Home
and Professional are identical except that Professional includes a few
features (mostly related to security and networking) missing from Home? Most
home users don't need and would never use these extra features and will see
no benefits by upgrading.

Also note another point, not included in any of the above: Professional
allows ten concurrent network connections, and Home only five.
