I was going to upgrade my son's machine from home sp2 to pro xp1, but message
said the version already installed is newer.... anyway to upgrade the
machine, or format and install??
Reformatting and installing cleanly *is* an option, but a lot of extra
work, and is way overkill to do this.
You have two better choices:
1. Uninstall SP2, do the upgrade, then reinstall SP2.
2. Create a slipstreamed version of XP Professional, including SP2,
and use it. See
http://forum.aumha.org/viewtopic.php?t=7262
or
http://www.webtree.ca/windowsxp/slipstream.htm
I would choose the second option.
But 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.
