Hi Diana
There exists nothing such as 'Windows 2000 Home'. However, you can update
from Windows 2000 Pro to Windows XP Pro and only Windows XP Pro, an Update
to Windows XP Home from 2000 pro is *not* supported.
More Information on Upgrading to Windows XP can be found here:

However, you don't really need to upgrade from 2000 to XP unless you need
one of the only-XP features. More info on Windows XP can be found here:

Don't be too sad that you cannot update to Windows XP Home as this version
is much less rich on features than the Pro Version. For example, the new
Smart Displays are only supported by XP Pro.
Hope this helps. Regards,
Fabio
