"Corporate" not only does not exist (as a name) - but even if you
consider the type of license as "corporate", it is still not a TYPE
of Windows XP. As far as I know, there are 4 (right now) "Windows XP
Versions".
Windows XP Home Edition
Windows XP Professional
Windows XP Tablet Edition
Windows XP 64bit Edition
I believe Tablet is merely a superset of Professional. 64bit is
likely more elaborate, but would qualify (network wise) as
Professional.
The differences are in the way you can "corporate network" (join
domains, etc) and remote with XP Professional and you cannot with
Home. So for a gamer, it has no bearing if they use XP Home or
Professional.
